Version 6 of the Internet protocol (IPv6) is a key enabler of the Internet of Everything (IoE). People, data, and things all need IP addresses to connect to the Internet. But we’ve already run out of IP addresses under IPv4, which dictates almost all (98.5 percent) of Internet traffic today. Even with all of the attention IPv6 has received, confusion and misinformation abound.
I’m extremely pleased to have Mark Townsley, Cisco Fellow and recognized industry expert on IP, explore IPv6 over a series of three blogs.
In these posts, Mark will demystify IPv6, discuss how to best make the transition from IPv4 to IPv6, and take a look “under the hood” of IP so that companies and industries can get the most value from IoE. Read More »

That was quick! I mentioned earlier in the week that, in any day, the IANA would hand out the last IPv4 address. Today it happened. And coinciding with the X-day, our panel discussed the true impact of the IPv4 address run-out. To mitigate it, Cisco’s Carrier-Grade IPv6 (CGv6) solution is designed to help enable a smooth transition.
One interesting observation I’ve seen is how something as obtuse and techie as IPv6 has generated so much interest in the main stream press – such as this article at the Wall Street Journal, Web Running Out of Addresses. Even my mother asked me about it on the phone last night “will the internets shut down?” No way mom…we’ve got that covered. The Internet will be Preserved, Prepared, and then Prosper!

I thought my children would never fully understand what a life changing experience the Internet has had on our society. They do not know life without it. However, with the imminent depletion of IPv4 address space, this possibility could still exist. When they are ready to subscribe to broadband on their own, will the Internet be ready for them to connect?
The Internet will soon be going through large-scale transition. The current Internet Protocol address scheme known as IPv4 is near depletion, with the “free” address pool held by the Internet Assigned Numbers Authority (IANA) due to allocate the final IPv4 address any day now. According to Geoff Huston, APNIC Scientist, the IANA will run out of addresses in February. And the first date for a regional Internet registry to exhaust its addresses is October 2011 given current utilization rates. Once the Regional Internet Registry (RIR) free pool is exhausted, the Internet will need to evolve because no more IPv4 address space will be available from the RIRs. Without a solution, Service Providers (SPs) will not be able to seamlessly connect the massive growth of new revenue opportunities from smart phones, tablets, machine-to-machine applications, and sensor networks.
In an ideal world, everyone would just switch over to the next generation of Internet protocol, IPv6. The IPv4 address shortage could be avoided, innovation and progress would continue, and the global economy would go on uninterrupted. IPv6 offers plenty of address space for every conceivable application.
