How to add PTR record OVH?

To update your Reverse DNS record, follow below instructions.

DNS (Domain Name System) translates an easily-memorized domain name into an IP address, allowing the Internet to work.

Reverse DNS simply maps the IP address back to the domain name.

In this article, we will show you how to configure reverse DNS in the OVHcloud Manager.

Configuring Reverse DNS on an IP

• To configure reverse DNS on an individual IP address, log in to the OVHcloud Manager, then click the IP option in the left-hand column of the page.

• Select the ellipses (…) button to the right of an IP.
• Then, click the Modify the reverse option from the drop-down menu.

• Enter the domain name corresponding with the IP address it points to in your A-record and click the Confirm button to save the changes.

• If the change is successfully made, you are all done. If the change is unsuccessful, check your A-record with your DNS host to ensure that the record is properly configured.
• Once you have configured Reverse DNS (RDNS), you may need to verify it works. To do this, you may follow the steps listed below.

Windows systems

1. Press the “Windows” key or open the start menu manually.

2. Search for “cmd” and open the Command Prompt.

3. Run the following command ( replace 192.168.0.1 with the IP address you need to verify RDNS on ):

nslookup 192.168.0.1

If you correctly configured reverse DNS, the output will be similar to the following example:

Name: host.example.tld
Address: 192.168.0.1

Unix-based systems

1. Open a terminal.

2. Run the host or dig command ( replace 192.168.0.1 with the IP address you need to verify RDNS on ).

host

host 192.168.0.1

If you correctly configured reverse DNS, the output will be similar to the following example:

1.0.168.192.in-addr.arpa domain name pointer host.example.tld.

dig:

dig +noall +answer -x 192.168.0.1

If you correctly configured reverse DNS, the output will be similar to the following example:

1.0.168.192.in-addr.arpa. 85524 IN PTR host.example.tld
