What are the (sub)domains for setting up a valid reverse lookup?
For setting up a reverse lookup through the Control Panel, our customers can use: 1. (sub)domains registered with another registrar using that registrar’s name servers 2. (sub)domains registered with another registrar using our name servers (external domain names) 3. (sub)domains registered with us In order to avoid abuse, the A-record of the desired reverse lookup domain must comply with the appropriate IP Address. A reverse lookup setup can take up to 48 hours to propagate over the whole Internet.
