Mr. Latif Ladid, the president of IPv6 Forum, left a comment on a previous post on my blog with the latest update on IPv4 exhaustion, only 12% of IPv4 address are left, that is 2% in less than 3 months, the new estimate is 769 days.
This this insightful comment:
The IP address space is down to just 12% with 534 M IP addresses or 32 blocks left. see http://www.potaroo.net/tools/ipv4/index.html
One of the most obvious and easily quantifiable incentives of the move to IPv6 is the growth and the continuity of the Internet and then the run to the bank for the remaining address space as it will be needed to have a secure dual stack transition which is the most secure transition and will be unfortunately the rich man’s transition. All others will tunnel which is not secure making it the poor man’s transition. Even the transition will aggravate the digital divide between the haves and have-nots in terms of security. The IPv6 Forum knew this problem 10 years ago and pushed ISPs to move earlier to manage a secure transition, but it takes patience and passion to make this happen.
