First off, Dynamic DNS, also known as DDNS, is a service that will instantly update your IP address (the A or AAAA record) if the host (device) changes it.
When your IP address’s lease ends, your ISP (Internet service provider) can change it automatically.
You can use DDNS to ensure that the device will remain accessible if you utilize it as a server. Otherwise, you won’t be able to reach the new IP address or determine it from a distance.
Without Dynamic DNS, if you are operating a monitoring server with a camera at home and you have been viewing the video from a distance, the connection will break the instant the ISP changes the IP address, and you won’t be able to see anything.
The DNS is made up of numerous DNS zones. Moreover, the DNS server you’re using can better handle several zones to manage the DNS namespace. So, we can say that a DNS zone is a subset of the DNS namespace that a single administrator manages. It’s utilized as an organizational segment to provide you more control over DNS things like authoritative namespaces.
For your domain to function correctly, you must point it to various servers, including web servers, mail servers, etc. This is accomplished by adding multiple types of DNS records to the DNS zone. So, the DNS zone is where all Domain Name System records are stored. It is also the lone component responsible for the existence of the Domain Name System (DNS).
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!
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.
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.
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.
