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.
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.
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.
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.
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.
