Canada and IPv6 (was: Ars Technica on IPv4 exhaustion)

I concur with Owen here.

6RD is a band-aid, but a pretty effective one to introduce IPv6 to the staff and management in your organization. When you get to native deployment, your engineering and ops staff no longer freak out when they see some IPv6 config. They can even debug ISIS and the IPv6 RR without calling you in the middle of the night! 

On the management side, they actually see IPv6 traffic in the nice monthly graphs, so they’ll remember to put it in the next RFP and even not to cut it from the next budget, if you’re lucky. 

And 6RD performance is quite good when implemented properly (2-3% hit on bandwidth, 1 ms in latency). What hurts are CPEs with bad implementations (bad option 212 implementation or no MTU reduction).
