Networking, DNS & DomainsConfiguring Reverse DNS (rDNS)
Reverse DNS (rDNS) is used to look up a domain or hostname from an IP address, which is the reverse of a normal DNS lookup. A correct rDNS record is very important for services like email servers, as it helps prevent your emails from being marked as spam.
You can manage the rDNS records for your server's IP addresses in the PowerPanel.
Accessing the rDNS Editor
- In the PowerPanel, go to
Network -> Nameserver. - Click on the Reverse DNS tab or section.
Follow these steps to set a custom hostname for your IP address:
- Find the IP address in the list for which you want to set the reverse DNS.
- Click the edit icon next to the entry.
- Enter your desired hostname (e.g.,
mail.yourdomain.com) into the field. - Click the change icon to save your changes.
Prerequisite: For your rDNS record to be valid, a corresponding forward DNS record (an A or AAAA record) must already exist. For example, if you set the rDNS for 1.2.3.4 to mail.yourdomain.com, you must have an A record for mail.yourdomain.com that points to 1.2.3.4.
