I just had a change to skip through our IPv6 logs from yesterday. There was a significant, but not huge increase in hosts accessing the site via IPv6. Usually we get maybe 200 or so hosts via IPv6, yesterday we got around 270.

Interestingly about 25% of the traffic (per IPv6 day as well as during IPv6 day) is due to hits to our rss feed. I will try to follow up on this to see why we get so much IPv6 traffic to it.

After an initial look at the logs, I didn't see any attacks via IPv6 against our web application.
