DNS (Domain Name System) Server

What is the DNS (Domain Name System) Server:

Domain Name Servers (DNS) are the Internet's equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.

DNS Port NO:

The reality is that DNS queries can also use TCP port 53

Forward Lookup Zone

Forward lookup zones support the primary function of Domain Name System (DNS), that is, the resolution of host names to IP addresses.

Reverse Lookup Zone in DNS

Reverse lookup zones support the resolution of IP addresses to host names. Although they are optional in most networks, reverse lookup zones might be necessary for certain secure applications that require the validation of IP addresses.
