World IPv6 Launch Measurements

From the Internet Society's most recent (January 16th 2014) round of IPv6 measurements, here again are the top 100 lists ranked by the two measures of (1) percentage of requests that used IPv6, and (2) total volume of IPv6 requests.

My past articles on this topic:
  * Measurements from December 12th 2013
  * Measurements from  September 17th 2013
  * Measurements from June 6th 2012

ISOC's blog post highlights that Deutsche Telekom, a large German telecommunications carrier, (of which T-Mobile US is a subsidiary*) has been experiencing very substantial IPv6 traffic growth. They've reached a figure of 15.5% of requests composed of IPv6 (to the select set of content providers providing measurement data). In terms of total volume of IPv6 requests, they are in 6th place behind five other large ISPs (See the second ranked list below). Comcast still leads the pack, followed by AT&T, KDDI, Free, and Verizon Wireless.

(*Note: T-Mobile's traffic is counted separately in the measurements from Deutsche Telekom)

Interestingly, while Verizon Wireless has a substantial IPv6 deployment, Verizon FIOS (their fiber-optic landline network) has made no visible progress in IPv6 deployment. Although many people, myself included, have noted this lack of deployment over the years, they were just recently taken sharply to task by folks on the NANOG (North American Network Operators Group) mailing list.

Looking at the rankings by proportion of IPv6 requests from each network, there is a new entry at the top - NYSERNet (a regional R&E network in New York State), coming in at a staggering 99.95%. On the Internet2 IPv6 working group list, I asked Bill Owens of NYSERNet if he wanted to comment. He claims that we shouldn't be too impressed because this is just the small NYSERNet office network and the backbone, with a relatively small population of clients. Regardless, I think it's a noteworthy achievement. As I've mentioned before, a number of universities and other educational organizations still show up prominently in this ranking. Two small american colleges, Gustavus Adolphus in Minnesota at 74.22% and Marist College in upstate New York at 65.77%! And Panamerican University, in Mexico City is at 66.22%.

Penn is slowly inching up at 45%. We'll have IPv6 deployed more extensively on our wireless network pretty soon, at which point I expect our numbers to go up noticeably.

World IPv6 Launch Measurements

The Internet Society has posted their latest IPv6 measurements (December 12th 2013). Read the section titled "Notes on network operator measurements" to understand how the measurements are being made and which content providers (Google, Facebook, Yahoo!, Akamai) are providing the data.

I've pulled out some of the data, and put together ranked (top 100) lists of networks by two measures: (1) percentage of requests that used IPv6, and (2) total volume of IPv6 requests. As I've done a few times in the past, I'm going to continue periodically writing these entries to have a snapshots in time of IPv6 deployment progress.

Many networks are posting some pretty impressive numbers for IPv6 usage. For the leading network in the %v6 category (the 1st list below), TOP-IX Consortium, an Italian Internet Exchange point has 86% of their requests to the participating content providers using IPv6! Several universities in the US R&E community are doing well too, Gustavus Adolphus College at 74%, Virginia Tech at 62%, University of New Hampshire at 51% among them. The University of Pennsylvania (my own institution) is posting a respectable 40% - we'll have IPv6 fully deployed on our wireless network in early 2014, at which time our numbers should go up substantially. There's an interesting story about why Penn hasn't had IPv6 on its wireless network for so long - I'm planning to write a separate article on that topic in the near future.

In the total volume category (the 2nd list below) Comcast now leads. John Brzozowski, Comcast's chief IPv6 architect, has written a more detailed article on their leadership position in IPv6 deployment. They are followed by several other ISPs: AT&T (US), KDDI (Japan), Free (France), Verizon Wireless, (US) Deutsche Telekom (Germany), RCS & RDS (Romania), Time Warner Cable (US).

Latest World IPv6 Launch Measurements

The Internet Society recently published results of their latest round (September 17th 2013) of IPv6 measurements. The measurement data is provided by Google, Facebook, Yahoo!, and Akamai. From the description on the website: "We present measurements of network operator participants in World IPv6 Launch, based on data received from major website participants, as described in more detail below. We present a simple average of the data received, and list all networks with measurements from at least two sources, with a simple average above 0.1%."

I find it instructive to sort the results by the percentage of requests from each participating network that are composed of IPv6. This is a pretty good indicator of how extensively these networks have deployed IPv6 to their end users.

Note: the measurements are only done for networks that have signed up as participants in World IPv6 Launch. If you've deployed IPv6 to your users, you should consider registering your network to take part in these measurements.

A Look at World IPv6 Launch Traffic Measurements

The World IPv6 Launch website has compiled a set of measurements at  http://www.worldipv6launch.org/measurements/. I'll take a quick look at some of them here, with a focus on universities.

The "Network Operator measurements" include data collected by Google, Facebook, and Yahoo! for access to their services on June 6th 2012 from the various network operator participants registered for the event. There were only 77 networks in total registered. I'm sure there are a number of other qualified networks that could have provided significant numbers of IPv6 users and traffic. I suspect the initial requirement that network operator participants be able to demonstrate that at least 1% of their traffic constitute IPv6 prior to the event likely dissuaded some potential participants from registering.

Different views of the network operator measurement charts require manipulating javascript controlled knobs at the website, so I can't provide a direct URL link to them. Instead, in the discussion below, I'm including the relevant screen captures.

View by Total Traffic 

The default view presents the participating networks sorted by total volume of IPv6 traffic measured, although the absolute volume number is not disclosed. Several large ISPs lead the list, with Free Telecom (France) occupying the top spot. AT&T (US), KDDI (Japan), RCS & RDS (Romania), Comcast (US), and Verizon Wireless (US) round out the next five. There is a significant disparity in the proportion of IPv6 traffic generated by those networks though, with Comcast seeing only 1.47% and Free seeing 17.35%. I suspect the numbers for Comcast will go up significantly as they turn up IPv6 on more of their home network customers during the coming year (the number was 1.5% on June 6th).  The US wireless carriers should also see their numbers go up as more of their users switch to IPv6-enabled 4G/LTE cell phones.

It's great to see a number of US universities (including my own) feature prominently in the top part of this list also - in ranked order: Indiana University, University of Pennsylvania, Virginia Tech, Louisiana State, and University of Iowa.

View by IPv6 Traffic Percentage

Sorting the table by the "IPv6 traffic percentage" column (the 3rd column below) produces some very impressive looking numbers. In this measure, universities start to dominate the rankings. The top two spots are held by Virginia Tech and Louisiana State, for which close to 60% of traffic constituted IPv6. Other notables include Marist College (53%), Indiana University (49%), RPI (47%), Penn (32%), University of Iowa (31%), Karlsruhe Institute of Technology (20%), & University of Phillipines Diliman (12%).  The effect of many of these universities having large parts of their campus networks IPv6 enabled and presumably large numbers of IPv6 enabled computers on those networks undoubtedly had a lot to do with these results.

It would be interesting to see more detailed measurement data from some of these extensively IPv6 enabled campuses about what proportion of their total traffic is IPv6 (as opposed to the subset of traffic only to a set of popular IPv6 enabled services). I hope to be able to share some data from Penn in the near future - we're currently dealing with some IPv6 traffic accounting bugs with a router vendor first. But our initial calculations are that we were seeing IPv6 account for 8 to 10% of the total traffic traversing the campus border during peak hours of the day. Even though the vast majority of the Internet is not IPv6 enabled, the existence of a number of popular and high-traffic generating services (Google, YouTube!, Netflix, etc) are likely skewing the numbers in favor of IPv6.
