Nope. You should get a ~/56. Even so, a /64 gives you ~18BillionBillion addresses. >Organizations will be provided /48s or smaller, but given the current issues >with routing /48's globally, I think you will find more organizations fighting >for /32s or smaller... so what once was a astonomical number of addresses that >one cannot concieve numerically, soon becomes much smaller. I can see an IPv7 Nope, organizations will go for PI ~/48s, and Verizon will be forced to stop filtering them. Oh, and IIRC - as it stands now, IPv7-9 are already shot (similar to IPv1-3) ... so IPv10 would be next up, in a century ... or four. >in the future, and doing it all over again...

As for the lessons learned - it is about scale. 32 bits isn't enough, double it 96 more times (or 32 more times for just the network side, if you prefer) and it is enough. /TJ
