IPv6 Act Now

We need to move up to Version 6 (IPv6) because, although the earlier version gave us 4.3 billion address combinations, we’re rapidly running out of them. You can see why. The Net’s early designers didn’t foresee a world where smart phones were connecting to the Web, and billions of new devices from TV tuners to refrigerators were slated for future Internet connectivity.

So what does the changeover to IPv6 mean for you? The typical consumer isn’t going to see much of a problem other than the occasional site that’s mysteriously slow to respond as changes are made.

Debunking myths that keep CIOs from adopting next-gen Internet addressing scheme.

For 15 years, Internet engineers and policymakers have been publicizing the need to upgrade the ‘Net’s current addressing scheme — known as IPv4 — to handle the network-of-network’s explosive growth. Yet many U.S. CIOs and CTOs continue to harbor misinformation that they use to justify why they are not adopting the next-generation IPv6 standard.

This issue is significant because the Internet is running out of IPv4 addresses. IPv4 uses 32-bit addresses and can support 4.3 billion devices connected directly to the Internet. The non-compatible replacement protocol, IPv6, uses 128-bit addresses and supports a virtually unlimited number of devices: 2 to the 128th power.

When the Internet was created in the 1970s, no-one would have imagined just how ubiquitous its use would be. Today, nearly every man, woman and child ‘connects’ on a daily basis and even humble domestic devices such as refrigerators and cookers can be connected to the Internet to aid daily life. In 2010, Gartner1 predicted that 1.6 billion smartphones alone will shipped, each having its own IP address – illustrating the scale of the issue. Nielsen’s Global Online Survey for 2011, conducted across 55 countries, showed that almost half of the Middle East’s online consumers (43 percent) plan to use a mobile phone to access the Internet while 29 percent intend to use a handheld multimedia device and 24 percent plan to access the net via an in-home video game system.

IPv6 is the next generation of web addresses which will eventually replace the current IPv4 system. The reason this next generation of web addresses was designed is because we are running out of addresses.

IPv4 is a 32bit address.
It supplies about 4,294,967,296 (4.3 billion) addresses.

IPv6 is a 128bit address
It supplies an astonishing 340,282,366,920,938,463,463,374,607,431,770,000,000 addresses!

Vint Cerf takes his title of Chief Internet Evangelist for Google seriously, and is knee-deep in several projects to bring the next versions of the Internet into being. These projects include pushing for worldwide IPv6 adoption, but they don’t include plans for an IPv7.

The IPv4 specification only allows a limited number of unique address; a little over 4 billion possibilities. And that’s the problem we now face. The IPv4 specification is over 30 years old and was developed long before the web evolved in the ubiquitous behemoth it is now. But running out of addresses didn’t come as a surprise. The same organizations who created the IPv4 specification have known this day was coming for awhile and developed a new specification called IPv6 to the supply the Internets addressing needs for decades to come.

In a ceremony in Montevideo, Uruguay, the Number Resource Organization (NRO) (www.nro.net), the global organization that coordinates the assignment of Internet addresses, announced that the last block of IPv4 addresses had been assigned on January 31, 2011. Does this spell the end of growth for the Internet, just as the industry has been gearing up for 4G wireless smart phones, and streaming video into every family room? Fortunately not, and just like the case of Y2K, the eventual exhaustion of the IPv4 address space had been predicted for some time, giving Internet architects plenty of time to react, and develop a course of action to address the challenge. But let’s back up and first examine the problem, before we look at the solution.

Comcast and Time Warner Cable, two major Internet service providers, will participate in the World IPv6 Day testing June 8 to help test readiness for the next-generation Internet Protocol.

Because the two companies are crucial gateways to the Internet for millions of people, their test will be an important–both for trying their own technology and for supplying some IPv6 users who can help other’s setup.

What: Last week the Internet Assigned Numbers Authority, operated by the Internet Corporation for Assigned Names and Numbers, handed out [pdf] the final pool of addresses available under Internet Protocol version 4, or IPv4 in a public ceremony. They were assigned to Regional Internet Registries, which are expected to distribute the remaining addresses.
