What is Domain Name System (DNS)?
DNS is a system used to convert hostnames that can grow up to 256 characters into IP. The host name, also known as the fully qualified name, indicates both the computer's name and the internet domain the computer is in. DNS resolves the IP address of a given machine name, allowing machines to communicate with host names on the internet.

What is the Purpose of DNS?
The purpose of DNS is extremely simple, it provides two-sided conversion between easily understandable and usable machine and domain names and machine IP addresses. Since it is not practical to use and remember IP addresses in daily life, the domain naming system is used.
Its main purpose is to respond to inquiries about the domain name or IP number from the network. For this purpose, "Berkeley Internet Name Domain (BIND)" software is widely used. When you want to access a site, DNS determines which site is where, which IP belongs to which computer, and you access it wherever you want.
