In fact, that's probably what the "router" on his network is (for 
example, it might be a "broadband router", or whatever those devices 
that you plug your DSL/cable/etc. line into, and that you plug your 
computers - or other Ethernet-equippend Internet-attachable devices - 
into, and that does NAT for those computers so they can all share the 
broadband connection; they tend to include a switch, which is what you 
plug the computers, etc. into).
