What is a SOA record in DNS?

SOA record is an essential and one of the most common DNS records. It is crucial to understand it properly. So, let’s explain it!

SOA record explained.

The SOA record is the beginning of the chain of authority, which is typical for the DNS. The short SOA stands for start of authority. From all the nameservers that you have, the SOA record will show which holds the original zone file. This server will contain all of the essential data about the zone. It will be your authoritative DNS server.

Information about the zone transfer and the email of the DNS administrator of the zone, and more is inside the SOA record.

DNS is a network of name servers, and all of them need to act together. Thus SOA record is extremely important with supporting to show up-to-date data.   

A query appears at the recursive DNS server. In case it can’t resolve it with the present DNS records, the recursive server will request from the authoritative DNS server for the updated records. Afterward, it will keep them for the time established by the TTL.   

If someone makes a change within the DNS records in the authoritative name server, this data should be renewed down the chain. There is a DNS notify list. It has IP addresses of the recursive DNS servers that are allowed to access the information. So then, they can complete a transfer without the need to wait for the refreshing interval to expire. The transfer itself is possible to be a full zone transfer (AXFR zone transfer) or incremental (IXFR).

The Structure of the SOA record

The SOA record is structured with the following elements inside:

  • Name – This is simply the name of the zone.
  • Type – This is the type of DNS record. In this case, it will be SOA.
  • Primary name server – Here is the hostname of the authoritative DNS server for that specific zone.
  • Default TTL – This number is a time period. It shows for what amount of time the DNS records are valid. The secondary DNS servers must perform a zone transfer when the time runs out.
  • Refresh rate – The number here shows in seconds how often the secondary DNS server has to visit the authoritative DNS server and review for changes.
  • Retry rate – The time the secondary servers will proceed trying to update if the zone transfer fails. If the time expires before they perform the zone transfer, the secondary servers will no longer answer queries. Their data will not be up to date.
  • Admin’s email – Here, it shows the email of the administrator of the zone.
  • Serial number – The serial number of the zone which secondary DNS servers check. And also determine whether they have to update their DNS records or not.

Why is it important?

The DNS SOA record for performing zone transfer. This record contains the most recent version of the DNS records for a specific zone. It is indicating when the secondary DNS servers have to update their information.

DNS SOA record is to show the top authority about a zone. The for the zone is the authoritative name server. This record is necessary, and only one should exist in a zone. If for some reason, you insert more than one SOA record, your zone will not function.

Domain Parking explained

The success of the Internet brought new possibilities and boosted creativity in different directions. It opened the door to alternative business’ strategies, like domain parking. 

What is domain parking?

Domain parking is the practice of registering a domain name without activating the common functions websites have. As a result, the owner has a static HTML web page, only informative, not interactive. Usually, the information those pages offer is the domain name’s objective and owner’s contact.

Why try domain parking?

You may wonder why invest in a domain name to have it parked? Here you have some reasons.

Selling attractive domain names. People realized the importance of having a catchy and memorable domain name for succeeding on the Internet. They started creating attractive domain names to register them, park them, and offer them to the best bidder. Most of the time, they register not one but many domain names to increase their chances of profit. Domain names for different industries, brands… After they own the domain names, they just publish their data and wait for potential clients’ contact.

Another scenario is a business website closes after some time. The website won’t work anymore, but it has a really attractive domain name. It can be parked and offered on sale. 

Get money from ads. Once you registered the domain name, you can simply insert ads on the landing page in exchange for a fee. You get profit from directing your visitors’ attention and clicks to those ads. 

Protect your business’ expansion and clients. When business owners have chances and plans for expanding, it’s not rare they register domain names using different TLDs (top-level domains). They register them in advance not to risk their further availability. And to protect their users from cybercriminals.

Think you have a successful e-shop, “example.de”, and you are expanding your presence first, in Europe and, in a second stage, the U.S. You can register this domain name with TLDs that get you close to your main markets “example.fr, example.it, example.es, example.nl, example.us”. It means you reserve them for your further use before someone could take them. 

In terms of security, it can happen that criminals know your business is growing and getting a reputation. They buy “example.us” before you to cheat people through the use of your brand. They build a fake site and invite users to spend on fake promotions. Users’ sensitive data could get seriously compromised while “shopping”.

To point your website is under development. Building a website is not a one-day task. If you get the ideal domain name, for sure, you can register it not to be gotten by others first. It will be parked until everything is ready for its official opening. For sure, you have found many “coming soon” landing pages while surfing on the Internet.

To inform changes to your clients. Online businesses can close, face a merge, find a better domain name, experience branding, market, administration, or ownership changes. To park the domain name to inform in its landing page the situation is useful not to confuse or lose potential clients.

Is domain parking free?

Domain parking is absolutely free. But to park a domain name, you must own it. That means you require the services of a registrar for them to check its availability and then proceed to register it for you.

Besides, the ownership is not eternal. It must be renewed, usually through a yearly fee. If you don’t renew, someone else can register the domain name.

Conclusion

Either as a security strategy or a profitable activity, it is interesting to have domain parking as an ace up your sleeve!

DNSSEC explained

DNSSEC can be spotted as an application to, in other cases, insecure DNS. It brings cryptography within and a complete line of trust. That is a guarantee for each level and implements top-notch security for your domain. 

What is DNSSEC?

The short DNSSEC is an acronym for Domain Name System Security Extensions. The primary DNS is reliable and fast, but its downside is that it lacks security. Back in the days when it was created, it wasn’t that of a problem. Later on, things change. 

The purpose of DNSSEC is to stop DNS cache poisoning. Also, modification of the DNS data is possible to happen if it is not activated.

It works with a combination of public and private keys. That way, every upper level can verify the level below. It is a built chain of trust. The chain breaks if one of the levels fails. This will mean that the data is no longer reliable.

Why do you need DNSSEC?

There are two major reasons to apply DNSSEC: 

  • Authentication of the data’s integrity. A significant element of DNSSEC is to examine that the data hasn’t been changed in any form after its origin (the authoritative server). A modification, such as a cache poisoning.
  • Authentication of the data’s origin. It is essential to know if the zone data is coming from the correct authoritative name server. DNSSEC won’t allow redirecting to malicious name servers.

What does DNSSEC do?

DNSSEC’s original purpose is to protect Internet clients from forged DNS data by verifying digital signatures set in the data. 

The resolver verifies the digital signature when a client enters the domain name. 

When the digital signatures in the data match those listed in the master DNS servers, the data can enter the client computer performing the request. The digital signature secures that the communication is with the same site you wanted to visit.

To verify the data, DNSSEC uses a system of public keys and digital signatures. It just adds new records together with existing records in DNS, such as RRSIG and DNSKEY. Their purpose is to digitally “sign” a domain with a method called public-key cryptography.

Nameserver, which is signed, has a public and private key for any zone. When a user makes a request, it sends data signed with its private key. The receiver unlocks it with the public key. When a third party attempts to send unreliable information, it won’t manage to unlock with the public key. Thus the recipient will identify the information as false.

How to use it? 

Most of the DNS hosting companies support DNSSEC but is not activated by default. Some domains can’t use DNSSEC at all, but almost all popular generic top-level domains and country-code top-level domains can. 

To start implementing it, you have to activate it on your DNS provider’s control panel. You just have to click on “enable” for each zone you want. Next, you will receive a DS record (delegation singer) and place it where your domain is registered. That will complete the chain.

What is IPv6?

Although many IT guys still prefer to work with IPv4, its replacement is already here, IPv6. The shortage of IPv4 is a big issue, and the world keeps going, so it’s time to let it go. The final countdown for IPv4 is running. Let’s talk about what IPv6 has in store to make the best out of it!

What is it?

IPv6 is the newest version (sixth) of the Internet protocol (IP). Internet protocols are sets of rules for devices to accomplish to send and receive data. This exchange of data occurs between a host and a destination (another host). Therefore, hosts must be identified. Their location is tracked through their corresponding IP addresses, and a route to reach their destination is defined for the complete data exchange to happen.

Something interesting it’s that IPv6 has been around for more than twenty years. It was officially introduced in 1995. A long time ago, the Internet’s success and the massive growth of devices demanding connection pointed out that IPv4 wouldn’t be enough to satisfy such need. IPv6 got developed and ready to use, but people seemed not ready to quit the use of IPv4. The transition to IPv6 is taking a long time.

Try to calculate the number of tablets, smartphones, computers, and the millions of Internet of things (IoT) that daily request an individual, unique IP address to connect to the web. That can give you a reference to understand how essential the role and the supply of IP addresses are. 

IPv6 features

  • IPv6 provides 128-bit addresses, the solution not to face shortages as it happened with IPv4. An approximated of 340,282,366,920,938,463,463,374,607,431,768,211,456 available addresses. Some will be reserved for special use, but still, the supply will be guarantee.
  • It will provide your network stateless address auto-configuration (SLAAC). It will automatically assign IP addresses for devices to connect. SLAAC will do the job of a DHCP server (dynamic host configuration protocol). The automation of this task is absolutely helpful in improving your network’s productivity.  
  • IPv6 incorporates IPSec. Through this Internet protocol security (IPSec), the recipient can check data’s origin. It involves a method for encrypting the communication, authenticating, and verifying the sender of data packets.
  • It avoids fragmentation of packets. Fragmentation was an issue of IPv4. The cause of packets’ loss, man in the middle attacks, and more. This has been solved in the new version. 

IPv6 address format

IPv6 addresses are built by eight sequences of four hexadecimal digits, all divided by colons. Every sequence represents 16 bits. 

Example, Google’s IPv6 address: 2607:f8b0:4004:0807:0000:0000:0000:200e

Why use IPv6?

  • If you own a network or a website, you need IP addresses for domain name resolution. Maybe you still use IPv4 and A DNS records for this purpose. But sooner than later, you will migrate to IPv6 and AAAA.
  • For setting up network routing at your home or business. Just consider that older devices might not support the new IPv6. This can be the only downside. 
  • For connecting multiple devices and IoT easily. To do this requires many IP addresses. A way to solve this it’s the use of network address translation (NAT). It maps multiple local private addresses to a public IP address as a previous step to transfer the information. Using it, you can skip this step.
  • For making different available services on the Internet, like web hosting, application hosting, etc.
  • IPv6 architecture is compatible with the future Internet and its 5G. Be ready from now for a smooth transition. 

Conclusion

Experience first-hand IPv6 benefits. Every day more devices support this IP version. Evolution doesn’t stop, and adaptation to the new conditions and standards is key to success!

DNS lookup: How to perform it? (Dig, NSlookup, Host command, Online tools)

There are many ways to perform a DNS lookup. You can do it through any web browser, even from a smartphone, or if you prefer, there are different built-in commands inside most popular OSes. These commands are the NSlookup command, host command, and dig command. You can use them for a quick check of your domain and troubleshooting problems.

DNS lookup with a Dig command

Dig command is one of the favorite commands for the majority of DNS administrators. It is built-in in most Linux distros, and you can access it through the Terminal application. You can use it to check different DNS records, perform a reverse DNS lookup, and even trace the route of a DNS query.

To use Dig for a particular DNS record type, use the following syntax:

dig domain name record type

Example with google.com as the domain name and MX as the type of DNS record:

dig google.com MX

You can use it with A, AAAA, NS, PTR, SOA, TXT records too.

Many options can refine your DNS probing. You can select the port you want to use, set the protocol for the lookup, modify the answer, and more.

NSlookup command

The NSlookup is a very popular command for DNS probing because you can find it built-in on Windows, macOS, and Linux.

It has less functionality than the dig command, and often IPv6 resolution does not work correctly but still function for many scenarios.

You can see different DNS types, select the port for the DNS lookup, increase the waiting time, probe domains and IP addresses too.

To use NSlookup for a particular DNS record type, use the following syntax:

nslookup -type=TYPE domain name

Example with google.com as the domain name and NS as the type of DNS record:

nslookup -type=NS google.com 

DNS lookup with a Host command 

The host command is another popular command on Linux computers. While it is a bit outdated, in comparison with the dig command, it can still provide you useful information about a domain name. 

Just like the previous software, this one has a command-line interface too. It also has many different options for modifying your DNS lookup. You can check a domain name or IP address, works with IPv4 and IPv6 too, you can adjust waiting time, choose retry number, and more. 

To use host command for a particular DNS record type, use the following syntax:

host -dns type domain name

Example with google.com as the domain name and CNAME as the type of DNS record:

host -cname google.com 

Online tools for DNS lookup

Many online utilities can help you to check DNS records. Here we have 3, that are safe, easy to use, and reliable.

Google

You can use Google’s Public DNS to query a domain name or an IP address. Visit dns.google.com, and there you can put one of the two. After that, you can see all DNS records, or specify which type of DNS records you want to see from A, AAAA, CAA, CNAME, DNAME, NAPTR, NSEC3PARAM, MX, SPF, and more. It also shows DNSSEC details.

DNS.computer

DNS.computer also works with IP address or domain name. What it can provide you as an answer is DNS resolution time from different locations in the world. That will help you see if you have a specific geographic region that you haven’t covered well and the service is slower there. You will also see the names of the nameservers the domain has, A records, and SOA records.

Mxtoolbox

The Mxtoolbox is another site that can give you in-depth information about the DNS records of a host. It works well with A, AAAA, MX, DKIM, DMARC, SRV, SPF, DS, TXT, and more DNS record types.

DKIM record explained.

Spam has become a daily nuisance for everybody. The number of spam e-mails can overwhelm our inboxes, reducing the space and chances for important messages to be received. Besides, they are a constant and real threat to our security. Scams, phishing attacks, malware can be attached to them, risking our personal information, business, and systems.

Fortunately, developers constantly improve and innovate with tools to defeat, or at least mitigate, these threats. DKIM is an example.

What’s the DKIM record?

DomainKeys identified mail, or DKIM by its initials, is a TXT DNS record type that allows domains to prove that the e-mails sent from them are legit via cryptographic authentication. On the receivers’ side, the DKIM record works during domains’ DNS queries. It verifies senders through the information set on the header. 

DKIM record is a way to prove e-mails can be trusted.

How does DKIM work?

A domain owner, who is in charge of its DNS records, publishes a public key (cryptographic). It’s contained in a modified TXT record. It will be the mean for recipients to check the authenticity of the e-mails’ sender.

Every time an e-mail is sent by a mail server (sender), it adds a DKIM signature into the e-mail header. That signature is a hash value, a unique textual string encrypted through a private key that only the sender has. The header registers information about the way the signature was created, and it includes two cryptographic hashes. One belongs to the message body and the other to the specified headers. 

When the receiver e-mail server gets an e-mail, it triggers a DNS request to find the public key from the sender domain. The DKIM signature offers data to find that key.

The sender e-mail server will find and decrypt the DKIM signature of the e-mail to its primary hash values. Those will be in contrast with the values gotten on the received e-mail. If there’s a match, DKIM will authenticate them as legit. 

What’s inside a DKIM record?

Every DKIM record holds inside the public key for the receiver to verify the e-mail and different signature values to execute its functions.

v – DKIM’s version.

a – it refers to the algorithm used to sign (rsa-sha1 or rsa-sha256).

b – signature.

d – domain name.

h – header fields. Here header fields signed are registered.

c – message canonicalization.

bh – body hash.

l – body length.

i – identifier (user or agent). 

q – DKIM’s default query method, DNS/TXT.

s – selector.

t – signature timestamp. 

x – expiring time for the signature.

z – header fields copied.

Benefits of using DKIM.

DKIM is easy to enable. It does not need three-party certification to work. It’s a self-certificate method.

Protect your users from e-mail forging. DKIM secures e-mails that your business sends from its e-mail server not to be forged or altered on transit. DKIM is a good tool for your business to prevent spoofing, phishing and to build a trustable reputation.

DKIM doesn’t affect e-mails bodies. The information to authenticate and verify is added to the header.

It works on domain names’ level. This means the DNS administrator signs all the outgoing e-mails. Not every single user has to do it when sending a message. 

It’s required to improve security through DMARC. There are more security tools that can improve your shield power, like DMARC. And to have a DKIM record is the basis for it to work.

Conclusion.

When it’s about security and the positive reputation of business, investments are totally worthy. DKIM is a useful record that, without doubt, you should enable on your domain. The benefits will spread to your business and clients. You can kill two birds with one stone!

MX record: Why is it important?

MX record is one of the common DNS records that is essential to know. Each action that you want to perform and is related to domains also requires DNS records for guidance. So let’s explain what the purpose of it is and why it is important.

MX record explained

You can probably find the MX record to be called a mail exchanger record. Don’t get confused. It is the same thing. The DNS MX record points to which server is arranged for accepting the emails that go for an exact domain. 

For example, if you want to send an email to Daniel@example.com, your device will have to know the location of Daniel’s email host. Therefore, it will view for the MX record on the name server of the domain. This server has the data for the domain example.com. After once you have it, your device will get the information about the server, which is arranged to accept the mail. After that, it will send the email there.

So to get it clear.

People need it to send you emails. More accurately to your domain. They receive the information about where the mails are supposed to be sent and the correct server. 

So, why are you required to have an MX record?

If you want to receive emails on an email that looks like this – name@yourdomain.com, you will need an MX record. Just specify which server that you have is going to be responsible for accepting your emails.

If you miss defining such a server, the sender will not know what to do. And probably that will lead to not even trying to send you the email.

Structure 

MX is a simple DNS record with the following elements:

Type (or record): In this case, it is MX.

Host: Here is your domain name.

Priority: Presented with a number from 0 to 65535. It sets the email’s priority and importance. The lower the number is, the higher priority.

Points to: Here, you specify the server which is receiving the domain’s emails.

Time to live (TTL): This is the time the MX record will be saved in the cache memory. 

How to check your MX record?

If you want to check your MX record, you can do it very easily. There are many different ways, including you can do it through a website. Another possible way is to use a command on almost any OS, like Windows, Linux, macOS, etc., or applications (iOS and Android). You could find a site that only asks for the domain name and the kind of record you want to see.

For Linux and macOS, use the dig command

First, you have to open the Terminal application. 

On macOS: You have to open the Finder, go to Application, open Utilities. There you will see the Terminal. Open it. 

On Linux (Ubuntu): You just have to press Ctrl+Alt+T buttons together. The Terminal will open up. 

Then inside it, you will have to type the following command. An important thing to know is that you start it by pressing enter:

dig example.com MX

*You have to change example.com with the domain you want to view. 

For Windows, use the nslookup command

First, you have to start the Command Prompt. Click on the Windows Start icon, and then write “cmd,” and you will view it in the results. Click on it. 

After that, inside the Command Prompt just type, the next command and press enter:

nslookup -query=mx example.com

*You have to change example.com with the domain you want to view. 

How does DHCP work?

The DHCP is an excellent illustration of how technology influences our everyday life. Both network administrators and clients benefit from it. It automatically designates IP addresses to the connected devices. It also keeps the information about them, and after they run out, it reuses the IPs.

DHCP explained

The acronym DHCP stands for Dynamic Host Configuration Protocol. It is a very effective solution for management and is commonly used on TCP/IP networks. Its work is to give IP addresses automatically and all the needed network configurations to connected devices to interact. The ones that benefit the most from DHCP are DNS servers, default gateway, subnet mask, and more.

It is important to note that the keyword is “automatically.” Tasks like that are usually performed manually by network administrators. In case they have to manage a small network, it won’t be a problem. But if they are in charge of handling big networks, it could be very overwhelming. 

Dynamic Host Configuration Protocol operates on a client-server model. For clients is required to have DHCP to interact with a DHCP server correctly. 

How does DHCP work?

Let’s view just the assignment of IP addresses.

Every device that connects to a network needs an individual IP address. Two or more devices are not able to operate with the same IP address. If it happens by mistake, one IP address to be assigned to two separate devices, the connection won’t work. It is possible only one of them to succeed to take it but the other one won’t.

Even when an IP address is assigned and the connection works, there is continuous monitoring beyond it. It is for various management’s purposes.

The IP address must refresh when it expires if the device needs to remain connected. Also, it is essential to examine when the IP address is not in use anymore. While a higher number of devices connected ask for an IP address, the administrators won’t run out of resources.

When you have DHCP, all of these duties are configured in the most beneficial form for you. They will appear automatically out of the need for human supervision. 

Benefits 

  • It automatically assigns IP addresses. The freshly connected devices have assigned IP addresses without the necessity for human interference. 
  • No chance of IP conflict. It eliminates the problem of two devices with identical IP addresses. If there is a case of IP conflict, both devices won’t be capable of using the network
  • It is easy to manage and set up. It is a simple and easy task to configure the DHCP server. 
  • No human mistakes. If people need to assign IP addresses manually, there is a significant possibility of human errors. While if you use DHCP, a tool is making every one of the IP address assignments. 

Conclusion

DHCP is an excellent technology. It is saving time and difficulties not only for network administrators but for everybody. For sure, it has its special spot in the term of networking. Its help with auto assigning IP addresses and managing them is crucial. If you decide to apply it, your network’s productivity will be genuinely improved.

DNS: What does it mean?

DNS meaning

Domain Name System (DNS) is a naming database system. It is locating and translating domain names into IP addresses. Imagine it is like a directory or even like a mobile’s contacts list. Each one of the names corresponds with numbers, and they are accurately matched. DNS directory is spread worldwide. This system operates daily. It helps to explore and reach millions of domain names every day. Without Domain Name System, we would have to remember each site’s IP address to visit it. This sounds nearly impossible, considering how many sites are out there.

Varieties of servers

  • Root servers – This is the start of the Domain Name System. Its sign is “.” at the very end of the domain name, yet everyday users don’t write it. The DNS resolution starts from there. After that continues to one of the name servers for the TLD of the domain. 
  • TLD name servers – Extensions like .com, .co .uk, .info, and so on are in the Top-Level-Domain level. TLD name servers will give information about which nameservers know the domain name you are seeking for. 
  • Authoritative name server. Here you can find the name of the site that you want to explore. The authoritative DNS name server has all the information for the site that you are searching. They will provide an authoritative answer. 
  • Recursive name servers. Their purpose is to answer queries. They may have the answer in their cache memory. If they don’t, the search will begin. It will start asking the other servers for an answer to the query.

DNS Records

DNS Records are an essential part of understanding Domain Name System better. So let’s see some of these records and what they do.

  • A record – indicates a domain name to IPv4 address.
  • AAAA record – points a domain name to IPv6 address.
  • MX record – reveals the email servers that are responsible for receiving messages for the domain name. 
  • NS record – points to the nameservers for the specific domain name.  
  • PTR record – Points an IP address to a domain name. It is the opposite of the A/AAAA record.
  • CNAME record – indicates that one domain is simply another nickname for another.

Free DNS vs. Premium DNS

You can see that there are free DNS and Premium DNS. In today’s world, Premium can actually be a very beneficial thing to have. For sure, one of the main reasons for choosing Premium is security and speed.

Directing traffic and looking up DNS records can take a lot of time, even if it’s simply about milliseconds.

If you want to try the free Domain Name System, you will find it comparatively slow. Premium usually offers better performance.

Additionally, if you, unfortunately, happen to be under a DDoS attack, Premium DNS can provide better security and availability.

But still, there are Domain Name System service providers, which can offer many of the benefits of Premium DNS, but in a free version.
