A few years ago I migrated some German websites to a new server and took the opportunity to make them accessible via IPv6. Later I wondered how many people actually access these websites over IPv6 and started collecting some data. Now, 15 months later, it’s time to have a look at it:
Blue, green and red points represent one specific website each. The three sites deal with very different topics and have different target audiences. The black line shows the average over all visitors which roughly follows the green site as this has by far the most visitors.
Some things that stand out are:
- Overall IPv6 accesses increased noticeably over time: Comparing February 2015 and 2016 there was an increase of about 6.5 percentage points (or 65%) for the average. Looking at the blue site, soon every fifth access will be performed over IPv6.
- The fraction of accesses over IPv6 heavily depends on the target audience of the website: There is nearly a factor of two between red and blue for February 2016.
- There was a slight drop in IPv6 accesses in early summer 2015 which is consistent between all three websites. I have not looked into possible reasons for this though.
Google also publishes statistics about IPv6 accesses. For them the global rate increased from 5.5% to 9.5% in the same time frame which corresponds to a rise of about 70% and is therefore pretty consistent to the data presented here. Per country only the current rate is available. For Germany this is with 21.6% particularly high and even slightly higher than for the blue site shown here.
