A new look on IPv6 adoption data was recently presented at the SIGCOMM conference in Chicago. The research, which was a collaboration between multiple groups, looks at over a decade of IPv6 data and notes that some measurements have seen a 400% increase in IPv6 traffic between 2012 and 2013. The data also shows a significant shift in the type of data toward HTTP & HTTPS content by end-users rather than server to server communication which was observed in earlier in the deployment timeline.

News reports have been circulating over the past couple of days that various service providers have hit the 512k route mark in their BGP tables on their routers and switches causing outages and other problems. A number of hardware platforms, notably older Cisco hardware, have default limits in their configurations which limit route tables sizes to 512k routes. When these limits are breached the older hardware slows down or otherwise stop functioning as expected. Cisco issued a bulletin in May to providers with workaround procedures for some platforms.
The growth in the global route table has been fairly stable over the past couple of years and this is growth has been expected for a long time and yet still Internet service providers were not prepared in time for this event.
Comcast has reported that they have fully deployed IPv6 dual-stack across their entire backbone broadband network and are working toward reaching 50% penetration to customers by the end of 2014. They have also stated that they are now carrying 1 Terabits per second of external to the Internet traffic calling out youtube as one of the primary sites which are using IPv6 natively.
Google has released a Doodle video animation with Vint Cerf explaining basic DNS and IP address management of the Internet, the formation of ICANN, and the IANA transition.
It is a fun little video and certainly makes the whole issue seem very simple. Unfortunately, real life isn’t that simple. There is a lot at stake with the control of the unique identifiers on the Internet. There is lots of history and politics going on behind the scenes with these changes in the Internet governance structure and how DNS, IP addresses, and other aspects of the Internet are managed.
LacNIC announced today that they have reached the equivalent of a /10 remaining in their free pool and have stopped regular allocations of IPv4 addresses to organizations in their region. Organizations will now only receive a single /24 to /22 of address space every 6 months until the pool reaches a /11. After the pool reaches a /11 only new members to LacNIC may receive a single /24 to /22.
A number of talks at NANOG 61 this week included some updates on IPv6 deployments. The links below will take you to presentations and also video of the speakers.
Akamai produces a security report annually and in their report this year they noted have seen a 10x increase in IPv6 traffic compared with the year before.
T-mobile described their IPv6 deployment for handsets particularly noting how all of their Android 4.3+ handsets are now IPv6 only using 464XLAT as the transition technology back to the IPv4 Internet. 8 million of their 49 million subscribers are now largely using IPv6 only. Furthermore, they report that 27% of their traffic is IPv6 and that 50% of the traffic from these 8 million handsets is completely IPv6 without any translation to the IPv4 world.
I also found these talks quite interesting, but aren’t related directly to addressing issues.
