text: can somebody see what you're surfing if connected by router? i'm receiving internet connection through a router from my neighbour's house. can he see only the ip addresses that i'm visiting or even more specific details (example: if i visit wikipedia, will he see only the ip address of wikipedia.org or can he also see the articles i'm browsing through?) depends.  if it's just a standard router, he won't have a log of anything.  if he would have a proxy server (unlikely), he could be logging everything you do.  my suggestion, quit being a theif, and stealing internet access, you can actually be charged and convicted of a crime doing this. pony up, and pay the bill like most of us.
