Of particular interest has been the adoption (or lack theorof) of IPv6 until the later part of the year. IPv4 space is now slated to be fully exhausted in early 2011, and people are starting to take notice. There’s been more mainstream media coverage, and requests for information related to IPv6 in the past 2 months than the first 10 months of 2010.
We’ve been running a native, dual-stack Ipv4 and Ipv6 network since 2008 and are pleased to see the adoption trends increase. We’ve also followed a mandate not to expand into any location without IPv6, and at the end of the year are pleased that we have native IPv6 support in every single one of our locations.
