And the Last 5 blocks of IPv4 /8 go to…

Keep moving along folks there is really nothing to see here….  nothing really new to report here, people always said the end was near, the real news is that they thought this day would have taken place 8 years earlier.  ..  below is my brief editorial of what took place Feb 3 2011.


AfricNIC, APNIC, ARIN, LacNIC and the last of the last goes to RIpeNCC < video press conference here.

Side note, APNIC has half of the worlds population and the majority of the IP4 addresses.

APNIC walked away with three /8 blocks (2 which were received earlier this year)and predict that it will hand them all out within the next 3 to 6 months.

A side note;

Technorati Tags:

A /8 contains 16,777,216 addresses or 24 bits just for the hosts.  Yes kids that’s over 16 million addresses to passed out.    In the early days of the internet, organizations were handed /8 blocks.

Stanford University was give but returned their allocated blocks to help delay this event, along with many others.  IPv6 was started in 1996, 15 years ago.

Lastly, you can obtain your own public IPv6 /48 block from  Very easy to do, hurry because there is only 340,282,366,920,938,463,463,374,607,431,768,211,456 (three hundred forty undecillion) go here for the pronunciation)) as oppose to the Four.something billion that IPv4 allocates.

I got mine two years ago, 2001:470:8b70::/4848. But /48 only provides me with routable networks. IPv6 assignments are for global routing and they use /64. So,  I now have 65,000 globally routable networks assigned. The various authorities are assigning /32 blocks, so tunnel brokers are currently generous with their offerings. However, this may not last.   lol


For XP users, IPv6 is NOT installed by default, you will need to implement the following command at the CMD netsh int ipv6 install then restart (its windows).

Network looking glass < this is where I got my IPv6 number.
