For example the reverse DNS entry for IP 1.2.3.4 would be stored as a PTR-record for "4.3.2.1.in-addr.arpa".

Reverse DNS is also different from forward DNS in who points the zone (domain name) to your DNS server.

RDNS can also be very useful when tracking down network issues and was the original driving force of RDNS.Without this sub-delegation from your ISP, your reverse zone will not work.Reverse DNS is mostly used by humans for such things as tracking where a web-site visitor came from, or where an e-mail message originated etc.When pinging a website or IP address, one part of the output is the server’s RDNS record.When you enter a domain name into your browser, the DNS system will find the IP address of the server the domain is associated with. It establishes what domain is associated with the IP address.
