By the way (Score 1)

One of the major french ISP has activated IPv6 last week, with autoconfiguration of user lan with global scope address. It's the first step for IPv6 here in france, and only geeks activated that option, but if a major application has success with IPv6 (read : a P2P file sharing that work well and only in IPv6), It is very likely that many people will activate it. The major problem is that people use their NAT as an "automatic" firewall, and i wonder the impact of global scope IPv6 address will have on machines corruption. Certainly a few impact at this time, but for the future, i don't know.

Anyway, get prepared for more and more IPv6 traffic, at least from france :)
