Hi Im trying to get a custom ip for my server i want to change my ip 111.111.111 (example) to game.minecraft.net (example) how would i go about doing this and is it possible to carry over ip's if i change from openvz server to an xen?
you need to register a domain name, which you can set to point at your ip. You can change it to another IP, but it usually takes a day or so for the change to go through.
If you have a dynamic IP that changes every reboot/disconnection from internet, you might wanna check out a service like http://www.dyndns.com or similiar. That service will keep your Domain pointer up to date for you.
there are lots of different companies where you can buy a domain name. google "domain registration" and add your country in the search and you should find a company in your country that sells domain names.
