[geeks] Common IP lease?

Shaw tells me that my modem is in line with the ones that they are
moving everyone to. You have told me it is pry not their fault, but
then I ask how to solve this problem. It is ridiculous to have to
reboot every two days, and I can find no setting that can lengthen
this. The problem renewing the lease might be related to whatever is
giving me errors when trying to access PGP keyserver's. I think it
might, though as I am told I have proven by this list how little I
know.

What I've been trying to tell you is that this may depend entirely on
what type of cable modem you have.

A "SURFboard" is a line of cable modems made by Motorola (er, General
Instruments).  The the really old ones used a proprietary protocol
over
the RF data link layer, and an integral dial-up modem for the return
path.  I doubt you have one of those.  The newer ones (eg. SB2100 and
SB3100 and so on) are DOCSIS compliant.

DOCSIS compliant cable modems are sort of like Ethernet bridges, much
like the older LanCity proprietary modems on which they're essentialy
based (though DOCSIS v1.2 is another leap forward).  The modem itself
DHCPs its own address, usually from a private RFC-1918 netblock if
the
ISP knows what they're doing, tftp's a configuration file, brings
itself
online, and then the Customer Premises Equipment can DHCP its own
address(es).

Even if Shaw is using an M$-NT based system for their CPE DHCP DOCSIS
server, it's highly unlikely they're to blame for your system's
inability to renew a lease....
