How to Change Reverse DNS for a VPS
This guide explains how to change the Reverse DNS record for your VPS IP address.
Reverse DNS, also called rDNS, is used to point an IP address back to a hostname.
Reverse DNS should usually point to a valid hostname that resolves back to the same VPS IP address.
Open VPS IP Addresses
To change Reverse DNS for your VPS:
- Log in to the Client Area.
- Go to My Services.
- Open your VPS service.
- Go to the IP Addresses tab.
Change Reverse DNS
In the IP Addresses tab, find the IP address you want to update.
Under the Reverse Lookup section, click the available action button.
If Reverse DNS has not been configured yet, the button may be shown as Null. If Reverse DNS was already configured before, the button may be shown as rDNS or Reverse DNS.
Enter the hostname you want to use as Reverse DNS and save the change.
Example Reverse DNS value:
server.example.com
The hostname used for Reverse DNS should already have a forward DNS record pointing to the same VPS IP address. For example, server.example.com should resolve to your VPS IP.
Propagation
Reverse DNS changes may not be visible immediately.
In most cases, the new Reverse DNS value should become visible within a short time, but DNS cache may cause some tools or services to show the old value for longer.
Verification
You can check Reverse DNS from your computer or server with:
dig -x YOUR_VPS_IP
Replace YOUR_VPS_IP with your VPS IP address.
You can also use:
host YOUR_VPS_IP
If the command returns your new hostname, the Reverse DNS record has been updated successfully.
