Ok, this is unofficial from a friend who works for RCN:

"Yeah, you are right about that.  Forgot that little detail :-)

We use 10. addresses for the modems because we don't have enough real
addresses.  Used to be the cm [cable modem] would get a real address and
so would the client machine, but then we were using 2 IPs for every
customer.  We sold so much damn cm service that we had to stop doing that.

As it is now, the cm gets a 10. and the cable modem is supposed to spoof
that and tell the computer that the default gateway (cm) IP is on the same
subnet as the client computer.  Sometimes the Macs don't like that :-)

Sometimes NT and Linux don't like that either, but the Windows 95/98/ME
crew doesn't seem to mind. "


Figured you might be interested after the recent talks....
