Interesting Graph - Decrease in 6to4?

Emile Aben

We have been measuring the number of clients connecting to www.ripe.net over IPv6 and made some interesting observations.

The percentage of users using IPv6 to connect to www.ripe.net for the last month is a bit atypical, which is good news and bad news. The bad news is that overall growth seems to stagnate a bit. The good news is that native IPv6 usage is still increasing and we see a drop in 6to4 (represented as a blue line on Figure 1 below). It looks like this is caused by the release of a new version of the Opera web browser early in March 2010, which doesn't prefer tunneled IPv6 (like 6to4 or Teredo) over IPv4 anymore. This is a good thing, but it has this strange effect on the IPv6 usage of clients as seen from web servers.

About the author

Emile Aben Based in Amsterdam, NL

I'm a system architect/research coordinator at the RIPE NCC, where I work in the science group. I'm a chemist by training, but have been working since 1998 on Internet related things, as a sysadmin, security consultant, web developer and researcher. I am interested in technology changes (like IPv6 deployment), Internet measurement, data analysis, data visualisation, sustainability and security. I'd like to bring research and operations closer together, ie. do research that is operationally relevant. When I'm not working I like to make music (electric guitar, bass and drums), do sports (swimming, (inline) skating, bouldering, soccer), and try to be a good parent.
