**What is Reverse DNS?**
It is the process of finding out which IP address a domain name is associated with. Its main purpose is to see the accuracy and reliability of the domain name. Especially in e-mails, it can be used to detect whether the e-mail address and domain name appearing in the sender part is really associated with the sender.
