Hello, whats the best way of preventing someone from voting twice? How do i get the users ip address? What if they are on a large network? will everyone on that network show the same ip? thanks

UPDATE: request.getRemoteAddr() and request.getRemoteHost() return the Server names, not the client's host name and ip. Anyone else got any bright ideas?

Ok, so lets forget about the voting twice thing. Im just trying to get the users ip address? i tried request.getRemoteAddr() and request.getRemoteHost() and think im getting the servers address. I have access to two separate networks and am getting the same IP address :(
