Re: Cogent - Google - HE Fun

[Owen DeLong <owen () delong com>]

I think it’s a little different from what you say…

I think Google already reaches Cogent for IPv4 via transit.

Google, long ago, announced that they would not be purchasing IPv6 transit and that they have an open peering policy 
for anyone who wishes to reach them. In order to avoid significant disruption, they haven’t terminated their IPv4 
transit contracts, but it certainly makes sense that they would not be pursuing IPv6 transit contracts.

The situation with Hurricane Electric is somewhat similar.

Google and HE are two of the most significant IPv6 networks out there. In the IPv6 world, Cogent is basically an 
also-ran so far.

The peering dynamics are different in IPv4 and IPv6 because the adoption rates and deployments in various networks have 
been different.

Cogent is sticking their head in the sand and pretending that their IPv4 peering status should carry over into IPv6 
automatically.

One of two things will eventually happen…

Either Cogent will win this game of chicken and the IPv6 networks that are not paying to reach them by transit now will 
start paying to do so, or, Cogent will lose this game of chicken and become progressively less relevant in the IPv6 
internet.

Personally, my bet is on the latter. For historical precedent, I refer you to SPRINT (AS1239).
