However, we should assist everybody without an AS and at least /24 to move to Cogent without renumbering. That means the blocks should be reassigned. That requires registry assistance.
To avoid routing table explosion, we probably need to identify adjacent blocks and encourage them to move to Cogent, too.
It seems to me that the recent discussion between Leo Bicknell and Lamar Owen is relevant. A network partition affecting hundreds of thousands (millions according to the Boston Globe article) is closely akin to a natural disaster. In this case, an _unnatural_ disaster. I remember presenting a paper at IETF over a decade ago about assigning IP addresses to exchanges instead of carriers. That would allow rapid failover, and promote competition. Therefore, I propose that we identify those ISPs moving from Level3 to Cogent that are also connected to an *IX. The IP block should be reassigned by the registry to the IX. We should encourage everybody else moving that requires a circuit change to connect to an IX where Cogent is present. That should help routing tables immensely! -- William Allen Simpson Key fingerprint = 17 40 5E 67 15 6F 31 26 DD 0D B9 9B 6A 15 2C 32
