Identifying different computers with same router

Is it possible to identify different computers if they're accessing the internet via the same router? For example if you have a poll and want to restrict voting to one per ip address this means that people sharing a house and therefore a router would all only be able to vote once between them right? Is there a way round this? Thanks

You are not able to access anything behind the router because it is a private IP address. Usually the ISP only gives one public address per house. So the router has to use a protocol called NAT which takes the private IP address and translates it to the public address.
