<p>PTR record or more appropriately a reverse PTR record is a process of resolving
an IP address to its associated hostname. This is the exact opposite of the
process of resolving a hostname to an IP address (<code>A</code> record). Example, when you ping a
name <code>mail.somedomain.com</code> it will get resolved to the ip address using the DNS
name <code>mail.mydomain.com</code> it will get resolved to the ip address using the DNS
to something like <code>192.168.1.5</code>. Reverse PTR record does the opposite; it looks
up the hostname for the given IP address. In the example above the PTR record
