Drop in IPv6 traffic

Thu Jul 9 14:34:53 UTC 2009

If I look at a tcpdump of our teredo relay which is announced to all our 
AMS-IX peers (and some partial and full transits), there's a lot of nntp 
and quite some torrent packets going over there, so it seems the 
majority of IPv6 traffic is due to content providers like XSnews 
providing 'freebies' to what otherwise would be a paid service.

We've seen the same with our Eweka/Highwinds partial transit, once we 
announce 2001::/32 there, there's suddenly a big increase in traffic 
over our teredo from other exchange points prefixes we get from them, 
heading to free IPv6 news services some dutch providers hand out.

Also, coincedence ?: http://www.sixxs.net/misc/traffic/
