IPv6 allocation plan, security, and 6-to-4 conversion

And, we're in sort of the same predicament - I have no choice on the
current infrastructure but to run IPv4.  IPv6 is a service we would like to
start to offer to new customers in this current infrastructure.  And to
existing customers who believe that they have the need for IPv6 and have
the equipment in their network to support it.

We may end up as IPv6-only on the customer side in new markets because we
don't have enough PUBLIC IPv4 address space to support a new market, but
that will STILL require private IPv4 for management and monitoring of the
equipment that does not support IPv6 yet.  (and yes, there's a lot of
equipment that is greater than 2 years old that still works and that does
not support IPv6)
