Re: Big day for IPv6 - 1% native penetration

2013 - the year of the NAT.  (the only way a single stacked address family is going to be able to talk to 
a single stacked member of a different address family...  and unless we start agressive reuse of v4,  this will
happen sooner than later (dual-stack is rate limited to the smaller of the address families -UNLESS- NAT makes
reuse possible... :)

But since NAT is going to be required -anyway-....

2013 will be the year of the NAT.

Dual stack works with "everything". IPv6 only access does not (with 
464XLAT it might). However, people are complaining that operators are 
focusing more on CGN and NAT44(4) than they are on IPv6. Which I can 
understand, but I believe we're getting closer to getting out of the dead 
lock. My hope is that 2013 is going to be the year we're going to see 
widespread IPv6 (dual stack) adoption on mobile devices outside of the US. 
It's looking good so far.

People are advocating dual stack now (at least that's what I do), for a 
future goal of IPv6 only.

The main problem with IPv6 only is that most app developers (most 
programmers totally) do not really have access to this, so no testing is 
being done.
