Yah, you got the answer right, except for using 'URL'.... URL is a 'Universal Resource Locator', that usually contains a domain name, etc.. IP address' (xxx.xxx.xxx.xxx) are actually the address in which a user is identified.
I'm used to it, people asking everybody but who they should for help, lol... I've gotten in trouble from forum owners and moderators for people asking about NWR on their forums, so I try to get people to do it where they are supposed to (and the most logical space).
