Adelphia Powerlink

[Dennis Ruzeski]

That's not accurate- They use ARP packets to determine who currently holds an address and checks it against lease time. 
The source is sent only as a mac address. The payload is essentially "Who has xxx.xxx.xxx.xxx? Tell yyy.yyy.yyy.yyy", where xxx.xxx.xxx.xxx is an address in the DHCP pool and yyy.yyy.yyy.yyy is the dhcp server. 

You can see this happen be capturing packets in promiscuous mode with ethereal or for a very cool look at your network, run etherape on a card in promiscuous mode.

One problem may be that the router has imcp (ping)
turned off. this causes their dhcp servers to assume
that the address is no longer in use and returns it to
the address pool. try allowinging ping and see if the
problem continues.
