A PTR (Pointer) DNS record is used for reverse DNS lookups. It maps an IP address back to a domain name, which is the opposite of what A or AAAA records do.
PTR records are commonly used by:
- Mail servers to verify the sending server’s identity and reduce spam
- Network troubleshooting and logging
- Security checks and reputation systems
PTR records are created and managed by the owner of the IP address (In this case, Voyager), not in the domain’s DNS zone.
Issue
If you are using your VPS to send email, you may find that some mail servers are rejecting email from your VPS because they are unable to do a reverse DNS lookup on the VPS IP address.
A PTR record allows a reverse DNS lookup to be performed on your IP address to resolve the hostname of your server or mail server.
Solution
A PTR record is created by the holder of the IP block, in this case, Voyager.
To have a PTR record created for your IP address submit a support ticket http://www.voyager.nz/support/contact and include your VPS ID, IP address that the PTR record should be created for and the hostname of your mail server.
