   It's not directly related to the issue at hand, but the GI/Motorola 
modems have been doing this for a while.  At least my GI SB3100 and 
Motorola SB4100 both had DHCP and a web server built in.
   There are two points to note about this.  One is that if you try to
grab a lease on your PC/router before the modem syncs with the cable
system, you'll get an address that won't get you anywhere.  OTOH you can
add an alias such as 192.168.100.xx _after_ getting a good lease and be
able to talk to your CM.  The information on the built-in web server can
be quite useful in tracking down connection problems.  The "Addresses" 
page (on a 4100), for example, tells one which CPE MACs have been seen, 
and in what order.  In some (all?) cases, only the first one in the list 
will actually be able to get out.

Show respect for age.  Drink good Scotch for a change.
