Re: chaging your @home IP address... could you take a bunch of them....probably... could you get something from it...maybe

Your IP address has nothing to do with their upload throttling. that is set
in the modem itself, by the provider end of the connection, with SNMP.
Run the docsdiag program on your modem, and you'll see the cap there.
Example:
DocsDiag v011209 Copyright 2001 Robin Walker rdhw () cam ac uk

Toshiba DOCSIS Cable Modem: HW 6.11; SW 1.7.007

Downstream channel ID                = 3
Downstream channel frequency         = 415750000 Hz
Downstream received signal power     = -1.5 dBmV
Upstream channel ID                  = 2
Upstream channel frequency           = 26096342 Hz
QoS max upstream bandwidth           = 192000 bps
QoS max downstream bandwidth         = 1500000 bps
SigQu: Signal to Noise Ratio         = 31.5 dB
Cable modem status                   = Operational
Upstream transmit signal power       = 41.5 dBmV
Date and Time                        = 2002-02-05,23:47:17.00+00:00
Configuration filename               = IP1.bin

I just read the @home IP change instructions in the Hacker's Digest and an
interesting idea came to me...

If @home uses IP addresses in parts of their bandwidth (upload) throttling,
then could you just take more IP addresses and get more bandwidth?

Now, I don't have @home :( so I can't test it, but can anyone out there test
this?

If so, I'd say the race is on to get @home addresses for more bandwidth..
