Research Request

Recently Lyndon's website has been getting a lot of junk requests. We have forms on our site where people can volunteer, ask for bumper stickers etc. But, recently I have been getting requests where people just put asdf into the tag line and link to a popup ad as their address. Obviously, this isnt a huge problem, but it has been annoying me. Does anyone know a quick and easy place to look up IP addresses. What these people failed to realize is that when they submit a false form I also am given their real IP address. I would just like to follow up with this and see who it is.

BTW- this happened in NJ recently, with the Republican's campaign spokesperson posting under multiple names and trolling the Dems blog.
