DNS stands for Domain Name System, it is used to alias NAMES to INTERNET PROTOCOL numbers. IE: "microsoft.com" is a domain name and 184.108.40.206 is one of the IP addresses associated with that domain name. As such, there are no "dns numbers".
Since you posted on this forum, you appear to be online, but in case you were signing in from your phone or a friends computer and you want your own internet connection, you might try your local phone or cable company first. Once your internet is installed
at your residence, connect your Xbox up via an ethernet cable or a wifi adapter. If you don't have a clue what any of this is, ask your cable or telephone company for in-home wiring service to help you get your Xbox connected.
