Adding a PTR record

A PTR record (pointer) maps an IP address to a domain name. It's particularly important for outgoing mail servers: most mail systems check the PTR record of the sender's IP address before accepting a message. If the record exists and matches the sender's domain, it's one of the factors that confirm the message is legitimate and help keep it out of spam.

Adding a PTR record

In your order dashboard, go to Settings → IPv4/IPv6 → PTR and click Edit.

Enter the domain name and confirm by clicking the checkmark.
