How to point a domain at your game server
Set your registrar's nameservers to ns1.enzonic.com and ns2.enzonic.com, then create an A record (for example play.yourdomain.com) pointing at your server's IP. For Minecraft, add an SRV record (_minecraft._tcp) so players connect without typing the port. From then on your address never changes — if you migrate regions or resize to a new node, just update the A record and players reconnect within minutes.
