A little break from the AD Interview Questions: Internet Protocol version 6 (IPv6)

IPv6 was created to address the “issues” & shortcomings of IPv4. From my experience, the acceptance & adoption of IPv6 has been slow at best. The threat of running out of IPv4 addresses hasn’t sparked a mad dash to an IPv6 Internet & internal networking.

The biggest highlight for IPv6 is the increased address space. IPv6 uses 128-bit addresses written in Hexadecimal format, so the new address space supports 2^128 (approximately 340 undecillion or 3.4×1038) addresses.

For a fairly detailed run down, wikipedia of course:

In one of my classes we covered IPv6 and a student noted IPv6 Test Day. So I decided to check it out.

The event is called World IPv6 Day & will happen on 8 June, 2011.

The jist of it, Major companies will turn on IPv6 access to there websites for 24hours. Among those companies, Facebook, Yahoo & Amazon. The sites will maintain the IPv4 information. So there “should” be no disruption in access to these websites. However, those sending IPv6 traffic should be able to pull up the IPv6 information.

Should in interesting.

As I was doing my research, I came across: The Internet Society (ISOC)

The Internet Society (ISOC) is a nonprofit organisation founded in 1992 to provide leadership in Internet related standards, education and policy. We are dedicated to ensuring the open development, evolution and use of the Internet for the benefit of people throughout the world.
