Motives for ISP? (IIJ hat on)

Why are you doing it so early?
For us, it is not early at all!

ISPs need to act proactively
By the time customers start asking for IPv6, we need a working backbone - need to be prepared
We need to gather operational experiences much earlier than customers
Break the chicken-and-egg problem

Our mission: make IPv6 the default IP protocol
