2012 North American IPv6 Summit this week

The 2012 North American IPv6 Summit is the largest regional IPv6 event this year. The Rocky Mountain IPv6 Task Force is hosting the event April 9 – 11, at the Grand Hyatt in Denver, Colorado.

Attendance at the event is up. While the usual reasons remain evermore apparent  — namely, IPv4 depletion and government mandates — a few new developments have urged IPv6 migration along this year:

  • It takes time to transition from IPv4 to IPv6; and that time is now. After over a decade of talking about IPv6, this is the year many industry experts see IPv6 trending from strategy to deployment.
  • In a study of 78 small to large corporate networks nearly a quarter of network devices are at or near a point where they will no longer be supported by the manufacturer — according to a recent Softchoice survey. As enterprises upgrade their network devices, many must redesign and future-proof for IPv6.
  • Vendors are finally creating IPv6-capable network appliances (like Riverbed’s RiOS 7.0), and network engineers need to know how those functions work.

Network professionals who scoff at an IPv6 transition aren’t exempt from its effects. If unchecked, IPv6 extension headers may affect router performance. In addition to performance, IPv6 security gaps remain,’s news writer Gina Narcisi explained in her most recent article — especially for those considering BYOD environments. Often times IPv6 networks are enabled on new mobile devices brought into enteprises. If a network manager does not know how to turn these “IPv6 shadow networks” off, they could open the door to unwanted traffic or malicious attacks.

If the resources above leave you with questions and you can’t make the North American IPv6 Summit, send your IPv6-related question to our IPv6 expert, Silvia Hagen at
