IPv4 (Internet Protocol version 4) is a popular and broadly used version of the IP. Thanks to the IPv4 addresses, it is possible to identify devices on the network. It includes 4 numbers between 0 to 255, divided by dots, for instance, 123.45.67.89, and it uses a 32-bit address space.
Thanks to DNS resolution, we don’t even think about what is happening when we click to visit a particular website. It is actually a complete process running behind the scene. It truly happens so fast, and because of it, we are not required to remember and type the difficult IP addresses. Instead, we memorize just the simple domain names, and we can easily connect to our favorite website. So, let’s explain a little bit more about this interesting process!
DNS resolution is a process that is triggered every time you want to connect to a website. After you type the domain name into your browser, it should be translated into machine understandable language. They communicate through numbers. For that reason, each domain name has to be translated into its corresponding IP address.
The Authoritative DNS server is an essential part of every DNS network. It stores all of the important DNS data, including the DNS records for a specific domain. That server could belong to a domain registrar or a DNS hosting provider.
