Is anyone still seeing a lot of IPv6 traffic? In the last 15 minutes, we've received an average of about 15mbit/sec from 2a00:1450:400b::/48 port 80. URL logs indicate it's probably Youtube; we're seeing requests like: GET /videoplayback... Host: o-o.preferred.google-man3.v2.lscache6.c.youtube.com ...which I see still has a AAAA. Looks to me like they've left some stuff IPv6-enabled, even if not the main website?
