A PTR (pointer) record maps an IP address to the domain name. It’s often called a “reverse DNS entry” because it converts an IP address to a name.
PTR records are mostly used as a security and anti-spam measure, to verify that a mail server address is allowed to send an email to a particular hostname. The reverse DNS entry checks if a server name is indeed associated with an IP address from where the connection was initiated.
In order to set up a reverse DNS entry that will connect an IP address to your domain (e.g., 127.0.0.1 should be mapped to yourdomain.com), you will need to contact your IP address provider to create a PTR record for the IP address.
Please keep in mind that PTR records are supported on our VPS and dedicated servers only. Still, it is also possible to create the PTR record on Shared and Reseller packages if you have a dedicated IP address. For that, reach out to us via Live Chat so that we can set the required PTR record.
