This article explains how to set up Reverse DNS, or PTR records, for your server from the customer Dashboard.
Setting Up Reverse DNS For Your Server (IPv4 & IPv6)
By default when deploying your server, a PTR record is set up for both the IPv4 and IPv6 address of your server. It uses the domain you specified during the deployment process. However if you want to change this, follow the steps below:
- Log into your Dashboard.
- From the top-right menu, click theÂ Servers link.
- Locate the server you are wanting to adjust the records for from the list, and clickÂ Dashboard on the right hand side of the table for that server.
- On the overview page for that server, there are tabs at the top. Select theÂ Networking tab.
- Towards the bottom of this page, you will see two entries that you can edit:
- IPv4 Reverse DNS (PTR) Entries
- IPv6 Reverse DNS (PTR) Entries
- To the right of each entry is theÂ Action column. Click theÂ Edit button and make the desired changes.Â ThenÂ Save the changes.
- The records should now be changed / added, and should instantly take effect.
Checking Your Reverse DNS / PTR Record
Simply run a 'dig -x' against the IP address:
dig -x ipv4.address.here
