This is one of the many reasons for this. I would argue the opposite; people won't turn it on otherwise, due to lack of knowledge or negligence. What I would also argue is that the API that opens a session should try all available address pairs in relatively short order - on the order of tens of milliseconds between new attempts - keeping in some scratchpad memory notes on what worked, and trying those first on a subsequent access to the same name. If IPv4 addresses are what work, so be it. Happy Eyeballs... _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
