Setting rDNS entries for dedicated servers
Setting rDNS entries for dedicated servers can be done via the Dedicated Server Panel at https://server.ip-projects.de.
Log in there with your account and switch to the section Data Center → Servers.
There you will see an overview of your servers.
Now search for the desired server and select either IPv4 or IPv6 via the button on the right side.
Now you have an overview of IP addresses and can also enter the rDNS entry for each IP address there.
As soon as an entry has been changed, it can be saved by clicking the "save icon" to the right of the input field.
Your rDNS entry is now set. The process is the same for IPv4 and IPv6.
