What is a PTR Record?

A PTR record (Pointer Record) is a type of DNS record that maps an IP address to a domain name, enabling reverse DNS lookups. It is the opposite of an A record, which maps a domain name to an IP address. PTR records are essential for verifying the authenticity of an IP address, particularly in email delivery and anti-spam measures.

While the main purpose of the Domain Name System is to point domains to IP addresses, a PTR record works in the opposite way – it associates an IP with a domain name. Because of its purpose, a PTR record is sometimes called Reverse DNS Record. The purpose of a PTR record is mostly administrative – it shows an IP is in fact used with a particular domain.

 

SiteGround does not currently support PTR records creation on any hosting plans.
