Unless there's a firewall using NAT or a proxy cache involved. I know for a fact that our internal network only ever reports the address of our firewall. We run an Internet kiosk of sorts so if two or three people hit your site from inside our firewall they will all look like the same person. We're not alone in doing this sort of thing.
