I'm not sure whether it was discussed on the mailing list. It *was* discussed in various WG meetings at RIPE meetings, both prior to implementing it ("this is the plan, what do you think about it?") and after that, taking criticism in, and trying to find a way forward.

[routing-wg]Four byte ASN notation
by Rob Evans 10 Dec '07

10 Dec '07

Folks, One of the items that was discussed during the working group meeting in Amsterdam was the relative benefits of using asplain, asdot or asdot+ to represent four byte autonomous system numbers. The chairs feel that the discussion tended towards favouring asdot/asdot+, which is already used relatively widely, but with the note that people do need to review their in-house tools and scripts to ensure they will work with numbers expressed in this notation. Cheers, Rob
