Reverse DNS

Reverse DNS lookup is the process of determining what hostname an IP address belongs to.

In contrast to the way that a regular domain name server works, a reverse dns swaps the hostnames with the IP addresses; they use the hostname to determine the IP addresses of certain websites. Without dns servers and reverse dns lookups, a great deal of the internet browsing that people do would not be possible; many IP addresses are not static, meaning that they do not .
