What are they going to do, visit each one of them? So good job they narrowed me down to 10,000+ houses. GeoIP says I am in 'Clarkson, Kentucky, United States', which is incorrect, I am in Elizabethtown Kentucky. So lets say someone does get your IP address, what can they do with it? Right now my IP is 67.140.131.201, so we will use it.

However this requires parcel permissions, and most reputable places will not attempt to ever do this. Parcel media is a bit different, as you can set individual URLs for each resident. Simply don't attach random huds(or random attachments in general, that's bad practice), and if it uses media on a prim, make sure you trust the creator. If they attach it as a hud that'd be a different story. Most cases these days will probably be over MOAP, in such cases you'll get one request for each person who clicks the media(emphasis on clicks, the target would have to click the MOAP, and there is no guarantee others wont click it as well), and then it isn't really possible to narrow down what IP goes to which resident. The only way to get a resident's IP address is to utilize media(parcel music/media or media on a prim), even then it requires the target to enable it, and whos to say others wont enable it as well?
