I don't deny that some registries have started allocating PI prefixes for large sites. That doesn't make PI the default model for small and medium multi-homed IPv6 sites, which is where our scaling problem will lie. I agree with Mike St Johns that this should be discussed on IPv6 lists, except for the uncomfortable fact that RFC 3484 makes recommendations for IPv4 too. Maybe the Internet Area can consider that aspect? Brian _______________________________________________ IETF mailing list IETF@ietf.org https://www.ietf.org/mailman/listinfo/ietf
