What's going on is the modem binds (or marries) itself to the MAC of the
NIC. That's how they control how many IPs, etc, a modem will give out. And
yes, cable companies have been using this for years. That's the cable
company mentality, especially Comcast. This is why I would rather just use a
Linksys or Netgear (or any other broadband router/modem) for my connection
to them.
Now I hear Comcast is pulling something about dis-allowing NAT'ing... They
keep thinking in the "cable" mentality, where they want to charge for every
connection, like they do when they charge for a connection to each TV set.
With networking, why would they want to think that? If you NAT, then you''re
sharing the connection, but it's still using the same bandwidth, whether
mutliple machines or one machine on the network.
