I saw ARP requests coming from the router and asking for the MAC of several 
other IPs of the same segment where my laptop was connected (in my case, 
192.168.9.x). I didn't catch any ARP responses...

Another probe I did was walking to a "public computer" in the hotel (some 
kind of internet-kiosk) and get the IP. The IP was in the same 192.168.9.x 
range. I didn't have time to get its MAC and try to configure my laptop's 
NIC with that MAC (although the switch should probably stop that... 
shouldn't it?).

I didn't have a look at this... although I'd guess it was rj-11... Next 
time I'll check it! :)
