And you're seeing remote st
my box (windows workstation) is connected to a cable

Where are you running this ARP command? On a router, on a workstation? What
does your network look
Good post. One minor correction, the COM21 modems are DOCSIS 1.1 certified.

Hi Sam,
The shared vs non-shared issue DSL providers mention is somewhat
misleading. In any residential cable or DSL network, you will
have stat muxing. In a cable network, this happens on the HFC
network. In a DSL network, this happens at the Agg router (the
one that terminates all of those

depending on the carrier, docsis could be implemented...I have not tcpdumped
my current connection (through att) but I believe att does filter.
a quick search on google yielded some docsis info but I didn't see whether
