A few weeks ago I shared my view on World IPv6 Launch impact: http://blogs.cisco.com/news/ipv6webimpact. Roughly two months later, it is time to look again, and time to reflect on what has been accomplished. I used to represent the IPv6 migration of the last 10 years as a classic Mexican standoff. Basically, no one (ISP, Content owner, Users, Devices, Enterprises) could see a benefit in being the first one to move, and the risk was perceived too…

Moving your network from IPv4 to IPv6 can be risky if you don’t close security holes In February 2011, the last blocks of IPv4 Internet addresses were allocated, highlighting the need for organizations everywhere to plan their transition to IPv6, the next generation Internet protocol. Because the move to IPv6 is happening gradually, applications will support both Internet protocols for some time—and so must your network. During the transit…

In the first installment of our series of IPv6 posts, we covered some basic differences between IPv4 and IPv6. In this post, we’ll talk about some common myths regarding IPv6. The initial IPv6 standards originated in 1998 with the publication of RFC 2460 – “Internet Protocol, Version 6 (IPv6) Specification.” The main intent behind IPv6 was to solve the issue of the limited address space available in IPv4. Over time, other features su…

IPv6 is becoming more widely deployed as the availability of IPv4 addresses continue to decline. In June, Cisco will be participating in World IPv6 Day, a 24-hour global “test drive” of IPv6 that is organized by the Internet Society. Hopefully this introductory post will give you a basic idea of how IPv6 works and some initial security concerns. In upcoming posts, I will explain in more detail the security impact on your network of v…

…site. You can also dig down into the methodology we are using to create the various rankings and percentages. Moving the needle Back in 2007 when Google began publishing its IPv6 measurements, native IPv6 deployment stood at 0.04%. Working together, the industry moved the needle 2500% over the past five years (while adding an additional billion users to the Internet during the same period). To help make this happen, two historic industry events…
