I don't want to argue this point, because I just don't have enough
information about the network. I seriously doubt, though, that all
those customers are all on a single /20 network (which would support
4096 hosts). Even worse, if there are routers there, too, it may need a
/19 (which would accomodate over 8000 customers). If they are not, take
my word for it...they are routed.
You never know.
Thanks to irony, my apartment is in a dead spot, where I can't get my
own company's wireless service, so I've got a cable modem at home. Right
now, my home router's IP address is assigned from a /20 - the router
reports my network mask as 255.255.224.0, and my default gateway really
is a couple thousand addresses away.
Being a cable company with positively obscene amounts of money, I'd
assume they're using some sort of fancy VLAN solution, or at least a
really smart switch. But heck, I don't really know. One of these days,
I'll be bored, and plug in the notebook, with Wireshark running, just to
see what kind of other traffic I can see out there...
