What is a PTR Record? 

A PTR record, or pointer record, is used to point your domain name to an IP address that’s associated with your server. A PTR record contains a hostname that is associated with an IP address. This allows DNS servers to route traffic to the correct location based on the hostname information.

Benefits of a DNS PTR Record Lookup

PTR records are widely used by Internet Service Providers (ISPs), as well as by large organizations and small businesses alike.

  • DNS PTR records are an important part of your domain name system (DNS). They provide a way to look up the IP address associated with a domain name.
  • They’re used for email authentication and other email-based services (like spam filtering)
  • They’re used in reverse DNS lookup, which is one way that email servers can verify that an IP address belongs to a certain domain name.
  • They make it easier for clients to find your website. Also, if you have an IP address that has multiple subnets or hosts on it, then adding a PTR record can help others find the right host.
