I have a cable modem and that little bugger sends out constant
broadcasts from 192.168.100.1, which is itself. It turns out
that the modem has a built in DHCP server. I set a filter on my
firewall to drop it all silently.
Perhaps you DSL modem as the same. I tested this by
disconnecting the modem from the public side and plugging my
laptop directly into it and running my dhcp client. I got an
address on that subnet and the gateway address was set to
192.168.100.1.
