Over the last several months, I’ve been pleased to invite Mark Townsley, Cisco Fellow and recognized expert on Internet Protocol (IP), to discuss IPv6 as a key enabler of the Internet of Everything (IoE). In his series of guest blogs, Mark has explained the basics of IPv6 and why it is important (“Demystifying IPv6”), and […]

We first talked about the Mapping of Address and Port (MAP) method to handle IPv4 exhaust and the transition to IPv6 last week. MAP is based on two IETF drafts currently in the process of standardization in draft-ietf-softwire-map (MAP-E) and draft-ietf-softwire-map-t (MAP-T). The real advantage with MAP is that it’s stateless and doesn’t require additional […]

The aim of the World IPv6 Launch was to spark a steady, sustained, growth of IPv6 usage leading up to and continuing after June 6, 2012. The continued growth since June 6 and the milestone reached this weekend is an indicator that this commitment had its intended affect thus far. Cisco now has its own AS (#109) on the network operator list, making it the first in the world that is participating in all three categories of the World IPv6 Launch. User activity as measured by Google hit 0.25% for the first time in March 2011. A year later, on March 10, 2012, it doubled to 0.5% for the first time. It's taken about 8 months to double that again to reach 1.0% today. If this trend continues, it will double again by mid next year and could break past 10% by the end of 2014. The trend is increasingly clear: If you are a network operator, network-enabled application developer, or anyone else that works with IP and are not running IPv6 now or don't have a plan in place to make it happen soon, now is the time to get started.
