I'm looking to host and register a new Showdown server, but I'm confused by all the names shown on https://pokemonshowdown.com/servers/ since I don't know how to change the URL from the IP address. Am I expected to be able to do this, or does Smogon change it somehow once I've registered the server? If I have to do it, could someone please offer some guidance on how to do it? I know what I'm doing setting up the server, I just don't know how to change the URL
