What should I consider when adding an external domain?

If you want to use the hosting with your external domain, but not with the name servers of easyname (ns1.easyname.com and ns2.easyname.com), you must make sure that the "A-entries" of your domain, respectively subdomain are pointing to the web server of easyname.

The IP address of your web server can be found in your easyname control panel under [Web Hosting] -> [Datasheet] in the line "Server IP address".

Please note, that external domains are not registered at easyname. They are only available for DNS and Webhosting.
