Question on Ipv6 address

Tue Mar 26 19:10:06 UTC 2013

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
that¹s cool.  But my question is what dial-up hardware supports v6? I am
*assuming* Cisco does.
