Reverse DNS is a system that allows a host to find the IP address of another host by querying its name servers. Reverse DNS is used to resolve a host name to its corresponding IP address.

The name servers in a reverse DNS system are usually authoritative for the domain for which they are responsible. For example, the name server for example.com would be authoritative for the domain name “example.com”.

This means that it would be able to provide the IP address for any host that is registered under the “example.com” domain.

Reverse DNS is often used to resolve hostnames in conjunction with Domain Name Servers. A Domain Name Server (DNS) is a server that provides name resolution for domain names.

When a user requests to resolve the name of a domain name, the DNS server will look up the domain name in its database and return the IP address that is associated with that domain name.

The DNS server for a domain name will also provide information about the domain’s name servers. This information is usually in the form of a list of IP addresses that are registered under the domain name.

By knowing the IP address of one of the domain name’s name servers, a user can query the name server using the domain name’s reverse DNS notation.

Reverse DNS is commonly used to resolve the IP addresses of hosts that are not registered under a domain name. In this case, the user will need to know the IP address of the domain name’s name server.

By querying the name server for the reverse DNS notation for the domain name, the user can obtain the IP address for the host that they are looking for.
