Please also refer to the results of the DNS64/NAT64 experiment that we ran at IETF 77. Users of the service encountered a bug due to parallel resolving in one particular operating system. We believe the bug is due to that particular implementation. Parallel resolving is still a Good Idea(TM), but this shows that implementing it correctly is not trivial. See: http://viagenie.ca/publications/2010-03-26-ietf-behave-nat64-experiment.pdf http://www.ietf.org/proceedings/77/minutes/behave.txt Hopefully it will be fixed by IETF 78... ;) Simon -- NAT64/DNS64 open-source --> http://ecdysis.viagenie.ca STUN/TURN server --> http://numb.viagenie.ca vCard 4.0 --> http://www.vcarddav.org _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
