Why do we still need IPv4 when we are migrating to IPv6...

As Steinar pointed out: You can help speeding up the process by enabling
native IPv6 access for as many as possible (all?) of your subscribers

I am sure you know that you can't completely skip the dual-stack phase,
and that's what you need to tell your manager. Sorry, but an opt-in 6RD
service isn't going to make IPv4 go away.  You need to force enable
dual-stack access for as many users as you can.  And if you dream about
doing IPv6 only, then 6RD isn't going to do, is it?  You need to roll
out native IPv6 access, and you need to do that before you can even
think about dropping IPv4.

Any delay in your dual-stack rollout translates directly to increased
cost of buying IPv4 addresses because it delays the magic cutoff day
when you can start selling IPv4 access as an opional add-on service.

(Note that I work for Telenor, which is one of Altibox' direct
competitors in the Norwegian retail Internet access market)
