On my network, our DHCP server gives out
addresses in this range: 10.0.3.200-250. But
over the last few days we've been finding iBooks
picking up numbers in the 10.0.1.10-20 range
which is bad because thats where our servers
are. We've tried turning off all the airports
but we still seem to be having problems. Here is
my question:
Is there any way to scan the network to find
where the offending renegade DHCP server is?
Use a network sniffer. Listen for DHCP traffic.
Check the source address of responders.
If your effected machines are Macs running OS X
you can also try Josh's suggestion.

Except that DHCP is not a TCP service and hence has no port that's open ;)
