[Techtalk] no gateway, yet it works!

[Meredydd Luff]

DHCP is capable of discovering a gateway automatically along with the IP, so 
the gateway won't have been specified in any of your config files. Also, 
ifconfig isn't the program to use to discover a gateway - if you want to look 
at the routing table, use "route". "route -n" is what I usually use, as it 
doesn't bother with reverse-lookups for all the IPs it sees. You'll see one 
down for "default" or "0.0.0.0" - that's your gateway.
