This observation moves the proposed AAAA-only mode into one of high risk. Rather than the benefit of reducing complexity, it becomes the danger of threatening interoperability. Let's note that the proposal is a change from a model that has worked solidly for 20 years and has not been a source of problems. While the proposal is for a mode that is appealing, it is not necessary. Methinks it is therefore time to respectfully retire the proposal. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net _______________________________________________ IETF mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf
