ah, the 0 bit in the IP address means it broadcasts on that subnet, ie if youve got a network with say 300 computers in it and theyve got .0 in the ip address, when you send data from one to another, it will actually send the data to EVERY MACHINE in the network. now you may think that dont apply to home users, but add more than 2 machines on the network (remember the gateway thingie counts as one) and start doing more than 1 thing at a time, and it will eat up your crappy 54mb of bandwith in no time at all and slow all the machines down.
