IPv6 Launch Day Wrap Up

IPv6 Launch Day was June 6th 2012.  As expected a number of high profile content providers such as Google, Microsoft (Bing), and Yahoo inserted DNS IPv6 records known as quad-A records for their main website into the global DNS.  I just did a quick check on a few of these sites and found their IPv6 record still are live and active.  With the quad-A records in place this allows those with native IPv6 connectivity to reach these sites wholly over IPv6.  This  is a great milestone, but still only a small step along the way to IPv6 adoption.

As I have discussed earlier, in this blog and in my other papers, I believe the main area which needs attention for IPv6 to become the dominate and majority protocol carrying Internet traffic is adoption by broadband providers servicing residential and commercial customers.  Until we see large deployments with tens of thousands if not millions of IPv6 customers by companies such as Comcast, Verizon, and AT&T the road to a viable IPv6 infrastructure remains somewhat uncertain.

Below are a few other articles with good wrap-up information from the IPv6 Launch Day event.

ARIN Returns IPv4 Addresses to IANA

After the adoption of the Global Policy for Post Exhaustion of IPv4 resources by the ICANN board, the ARIN board has decided to return to IANA some of the resources that it had received back from legacy address address holders.  All of this space is the equivalent of a /8.  The largest part of this block came from Interop who returned almost a /8 to ARIN in 2010.  The long-term effect of this will bring ARIN’s IPv4 exhaustion date closer to RIPE’s exhaustion date which is expected this year.

From: Geoff Huston’s IPv4 Address Report

Presumably IANA will now proceed to reallocate this address space to all 5 RIRs according to the global policy.  However, given that some RIRs currently have a sufficient free pool one would expect them to decline the reallocation of space, thus a majority of the space seems likely to go to either APNIC or RIPE.  APNIC’s current IPv4 policy, however, would only allow blocks of size /22 or smaller to be allocated.

From a practical perspective, it seems like it would have been more reasonable for ARIN to just return the largest blocks and reallocate the small blocks to new or existing IPv4 address holders.  However, the final /8 allocations process by chance ended up giving ARIN a much larger supply than was needed compared with the other RIRs.  Thus, it seems likely the ARIN board felt compelled to “right this wrong” as well as to continue its previously existing operational procedure to return to IANA IPv4 space received from organizations prior to ARIN’s formation.
