RFC 943: 42 THINK-AS [BJN1] [BJN1] Bruce Nemnich TMC b...@mit-mc.arpa I have no idea which registry was maintaining AS number registrations when AS42 changed hands. I suppose it's possible the current registrant acquired or merged with whatever entity THINK refers to, but I doubt it, so it seems likely at least at one time transfers were reflected in updated registrations. I bet Douglas would have been tickled. Cheers, Dave Hart
