I have an IP masking service which updates to my changing IP. Is there a way for a server to use this?
By "Ip masking" you mean a dns service. Like myserver.mydomain.net instead of an IP ... or is it some sort of VPN ? The only problem would be disabling the possibility for players to add the server in their favorites i think since the IP changes and favorites are probably saved by their unique IP ...
If what you mean is that you have a dynamic ip (changing) and you use a noip server there are no problems, we have been using it for years.
