If you’ve been paying attention you will have heard that the world’s supply of IPv4 addresses is running out. While this isn’t a Y2K situation, it’s an important watershed in the explosive growth of the Internet.  As the world shifts from an Internet of People and Places to an Internet of Things the foundation of the Internet is changing from IPv4 to IPv6.

Is Cisco ready to address the issue?

We’ve had working IPv6 code since 1996 for starters.  So we have some very seasoned support engineers who can answer all your questions at the IPv6 Cisco Support Community site. If you need help assessing your business needs, you can use our professional service offerings to  preserve your investment, prepare for the impending change and implement a long-term planning process.

How does an IPv6 address affect your experience?

No one really knows the full answer. That is  why the Internet Society is sponsoring a global test run  of  IPv6 use on June 8th, known as World IPv6 Day. It’s an opportunity for many of the major technology industry players to conduct an unprecedented experiment by enabling IPv6 on the Internet.

In fact, next Tuesday, on May 17th you should tune into a free IPv6 Webcast to hear about steps you can take to prepare your network for World IPv6 Day.

What does this shift in Internet addresses mean to you and your business?

It means that IPv4 addresses will become increasingly expensive.   The Internet of Things has fueled tremendous growth in the number of devices which need a network address. It’s not just a PC at work and one at home as we had a few short years back. Today  everything needs addresses including your smart phone, tablet, the chips in your car, sensors in bridges and roadways, security cameras, IP phones and more.

In the not too distant future, smart devices, new applications and new businesses will only be issued IPv6 addresses. Make sure you’re ready for this change.

What can you do today?

As I said, this isn’t a Y2K situation. The Internet of Things won’t come to a screeching halt. But your business network, or your customers, may start to experience less than optimal service or connectivity due to the industry’s lack of knowledge about how old IP addresses and new IP addresses will behave together.

Don’t risk having “good enough” technology and products. Get involved with the biggest network transition of our lifetime and start your adventure with Cisco Services expertise.

  1. IP6 remains in the hands of techies and geeks. Rest are not bothered. I was wondering if people, who are supposed to implement IP6, are really doing something or waiting for the ticking bomb to explode? I read news that IP4 has already run out from Asia.

    I, as an end user, already feel the heat when I try to get Static IPs which are expensive and not easily available.

    Great question, Ajay. Now that IPv4 addresses have run out, many service providers are finally swinging into action. Comcast in the US, Free in France, Swisscom in Switzerland and NTT in Japan are just a few of the providers rolling out IPv6 at a large scale.

    On the web server side, World IPv6 Day provides an excellent platform for web providers to get some experience rolling out IPv6 services on the web. Many web providers already offer IPv6 and more are coming online all of the time. See http://isoc.org/wp/worldipv6day/ for a partial list.

    Most recently, World of Warcraft enabled IPv6 in their hugely popular massive online multiplayer game. The use of native IPv6 has the potential to reduce delay introduced by NAT and allow direct peer-to-peer connection between players without relying on centralized servers.

    All modern operating systems since Windows Vista, Windows Server 2008, iOS 4, MacOS 10.2 and Android 2.1 have IPv6 installed and enabled by default, patiently awaiting their first ICMP Router Advertisement.

    So, there is a lot going on! Who is your ISP? Ask them when they will provide IPv6.

  3. I find lot of DNS hosts have not yet implemented the ability to add AAAA records meaning errors are throw when trying to add ipv6 to your zone

  4. It does suck that ipv4 is running out. But they can free up tons of them by moving cell phones to private Ip addresses. Or move more home connections to private. Although cell phones are probably the biggest waste of them all.
