Can somebody get my name and home address once they have my IP number?

MSN Web Messenger is a browser-based messaging program that allows MSN users to instant-message people on their contact list, from computers that do not or cannot have the program installed (ie public computers). Web Messenger was launched in August 2004, and is convenient for people who are using the internet away from home, or own computers that are some way incompatible with the MSN program. On the contact list for MSN Messenger users, the status of somebody using Web messenger is either displayed as a globe (), or by appending the word (Web) after their name, depending on the version of MSN Messenger used.
