We experienced a strange problem with one of our Cisco 6503 routers -

What I've heard is that the driver is IPv4 exhaustion: Comcast is
starting to have enough subscribers that it can't address them all out

That really makes sense - on an incredibly smaller scale (and I mean MUCH
smaller scale), we operate cable modem in two small communities - currently we
use 3 IP addresses per subscriber. One for the cable modem itself, one for the
subscriber (or more depending on their package), and one for

They'll need to be soon to keep up with others in their space (not that they
generally compete directly thanks to franchise laws), although I'm not sure
how the data side of things is handled for MVNO's, normally they don't have
any network of their own:

Typically the CPE address is private, not sure why they would use a
public IP. The MTA (VoIP) part of the modem would need a public IP if
