A PTR record, also known as Reverse DNS or rDNS, maps an IP address back to a hostname
You can manage Reverse DNS for IP addresses assigned to your Dedicated Server directly from the Ozonti Client Area
192.0.2.10server.example.comLog in to your Ozonti Client Area and navigate to your active services
Open the Dedicated Server containing the IP address you want to configure
From the server management page, locate the Reverse DNS section
The IP addresses assigned to your server will be displayed
Locate the IP address you want to update and enter the fully qualified hostname you want assigned to it
192.0.2.10 server.example.comserver.example.comhttp://, https://, ports, or URL pathsSave the Reverse DNS configuration to apply the new PTR record
Once the change has been processed, the IP address should resolve back to the hostname you configured
You can verify the Reverse DNS configuration using the following commands
dig -x 192.0.2.10nslookup 192.0.2.10If the IP address is being used for a mail server, the forward DNS and Reverse DNS records should normally match
| Record | Configuration |
|---|---|
| A Record | mail.example.com → 192.0.2.10 |
| PTR Record | 192.0.2.10 → mail.example.com |
If you are unable to configure your PTR record, please open a support ticket and provide the IP address and the hostname you want configured
