Dear DNS Coach,

What is a PTR Record used for?

First of all, let’s discuss what a PTR Record (or Pointer Record) is before we go into what it is used for.

A PTR Record is used to map a network interface (or IP) to a host name. These records are most often used for reverse DNS.

Reverse DNS (rDNS) is the method of resolving an IP address into a domain name, just as DNS resolves domain names into associated IP addresses.

The end result of this record is that: points to mx2.dnsmadeeasy.com.
