Justin,
Dial-up modem is just a layer 2 device with no IP address. Just think of =
it
as a converter, its sole function is to convert the telephone line to
something your PC can use, in this case, Ethernet. Both IPv4 and IPv6
operate on the layer 3 of the OSI model which is taken care of by the =
RAS.
So basically any dial-up modem support IPv6.

I don't mean to hijack the thread so if someone wants to open a new one
that=B9s cool. But my question is what dial-up hardware supports v6? I =
am
*assuming* Cisco does.
