What? Is this true? Will we actually have to start learning IPv6? Well that is definitely what its starting to look like. Based on the below information there are only 7 blocks left.

Yesterday, the Internet Assigned Numbers Authority (IANA, part of ICANN), allocated two blocks of 16.8 million IPv4 addresses to the RIPE NCC and another two blocks to ARIN. The RIPE NCC and ARIN are the Regional Internet Registries that give out IP addresses in greater Europe and North America, respectively. This brings the global pool of still available “/8″ address blocks that IANA maintains from 11 down to 7.

What does this mean to the general public? Not too much, but it means a lot to us Engineers and Techs, start brushing up on IPv6 asap. Check out the IPv6 Wiki Page, its chalked full of good information. If your more of a book person y ou can check out IPv6 for Enterprise Networks from Cisco Press.
