IANA this morning did a formal hand over of the last 5 /8 blocks. The Internet Society has a nice statement on the event. Here is ARIN’s press statement. Oddly enough, there doesn’t appear to be any formal statement on the IANA website. If you aren’t seeing the swimming turtle on the upper right of our page you aren’t using IPv6 to view the site. It might be time to start working on plans to get on IPv6.
