to correct something I just miswrote:
- if you define it as the ability to "plug and ping" small networks
into the Internet, then (as far as I can tell) we still need
a small piece of protocol beyond IPv6 to have a "pure IPv6"
plug-and-ping solution. in the interim, either PPP or DHCP
will give you an IPv4 address; this combined with 6to4
gives you a /64 on a plug-and-ping basis, and the protocol work
for this is already done.
it should read
"...this, combined with 6to4 gives you a /48 on a plug-and-ping basis..."
