Is it possible to get a ip like pvp.yourservername.com for free running a server from your computer not a host just wondering thanks!
Nope, you need to purchase a domain name from a place like this. Unless you register for a free one, which doesn't use .com as a TLD, from a place like this.
You can however get a pvp.servername.tk for free. Edit: Oh you already posted that You just set the dns records as following Record type: A Subdomain: pvp. IP: (Server IP)
