I saw the strangest thing (to me, anyway) on my verizon DSL account.
It seems to assign a single DHCP IP address to a mac address, then holds
it across reboots, shutdowns, etc.
While the lease is "not released", no other machine is recognized. All
DHCP request packets are silently ignored.
A modem reset would not clear it.
Attempting to use another mac address to get a lease (swapping out a
machine) just gets ignored requests...no response at all.
But if I plug my Mac Mini in, it gets the address right away. Every time.
The Mac has a ipconfig release command and it actually works...just
change the proto from DHCP to BOOTP...after releasing the address from
the Mac, I could connect a FC4-F7 back into the modem and get an IP
right away.
I suppose the Mac had the lease all along and finding the release
command opened up the modem for another mac address? Nor sure what was
happening. Seems ok now.
I see a lot of people complaining on the web about not being able to get
IP addresses for their routers from cable modems, DSL modems, etc...I
wonder how widespread this issue is.
