mail from Cogent: 
Dear Cogent Customer,

Thank you for contacting Cogent Customer Support for information about the Google IPv6 addresses you are unable to reach.

Google uses transit providers to announce their IPv4 routes to Cogent.

At this time however, Google has chosen not to announce their IPv6 routes to Cogent through transit providers.

We apologize for any inconvenience this may cause you and will notify you if there is an update to the situation.

Mail from Google:
Unfortunately it seems that your transit provider does not have IPv6 connectivity with Google. We suggest you ask your transit provider to look for alternatives to interconnect with us.

Google maintains an open interconnect policy for IPv6 and welcomes any network to peer with us for access via IPv6 (and IPv4). For those networks that aren't able, or chose not to peer with Google via IPv6, they are able to reach us through any of a large number of transit providers.

For more information in how to peer directly with Google please visit

best regards

I just noticed that I am NOT getting IPV6 Google prefixes though Cogent at all. I was told google pulled all of their peering with Cogent?   If I bring up a SIT tunnel with HE, I get the prefixes but at horrible speed and latency .. anyone else?
