AT&T Broadband

[junk]

I have been a customer of AT&T Broadband / MediaOne in Cambridge since 1999.

I have just moved to a different AT&T Broadband city and had just had a
'Basic Installation' done - this is where the cable contractor just brings
in the line from the pole, check for a good connection to the modem and then
leave. When I called in for activation, I was asked for the MAC address for
my NIC. When I told them I was using a router - the guy at AT&T said that
then he would need the MAC addresses of the NIC as well as the router.

My question is this:

Is the AT&T person simplly just needed to fill out all the blanks on his
form, or is AT&T now doing something with the MAC address of the NIC? I have
been swapping differenet boxes running all sorts of OS's behind the router
without any problem.

Just curious.
