Daniel, Have you or someone from RIPE participated on the IPng mailing list? Have you or someone from RIPE participated in the IPng WG meetings at the last three IETF meetings? The reason I ask is because we have done technical analysis on this and have had much discussion. I think discussing the reason for going with a 13bit TLA needs to be brought out more and doing and checking that is prudent. But the architecture and reasoning has had many technical discussions. I would like to understand as a WG member if you or RIPE did not agree with the results (which I would think we would have heard before now) or if you or RIPE have not been part of these open public discussions. It could be we need to point to the mail archives and the GSE reasoning paper done by Thomas Narten, Lixia Zhang, et al from whence this essential proposal came from based on a WG meeting in Mountain View about a year ago? I am trying to understand if this is an educational effort on our part as a WG group? thanks /jim
