Question: Who registers new web addresses besides the US Government? 

Answer: If you want to get your own domain name (like yahoo.com) then search Yahoo! for "domain name registrar"\n\nSome web site hosting companies can register a new domain name for you when you purchase web site hosting service from them. (Most web sites require a separate "web site hosting" service to store their web pages.)\n\nSince you were not specific enough, I hope that this answers your question. :)
