So im about to create a server and i wanna ask if i can get my own IP after i create the server. Thank you
Yes, but it would always end on something like .hostorde.net, .mcalias.com, .gamename.net or .mc-srv.com. On the other hand, if you already own a domain, you will totally be able to use your domain as the termination, like "play.electriccurrent.net" or "server.electriccurrent.net".
I know this is a silly question to ask but how can i own a domain (Im feeling like a noob when ask this question )
You buy it. They usually come with a website host service, but you can also only buy the domain, in places like Godaddy.
For a free subdomain, you can go to http://hosthorde.com/free-subdomain If you wish to use your own domain, we offer a guide for getting started here: https://www.hosthorde.com/forums/resources/setting-up-a-custom-server-address.63/
