Why exactly is it necessary to have the IPv4 and IPv6 number space be consistent? What is the technical requirement/benefit here? My own sense is that this would be "nice to have", but it is certainly not required, and I don't see that having the numbering space be strictly synchronized as providing compelling technical benefit. What am I missing? Thomas _______________________________________________ Int-area mailing list [email protected] https://www1.ietf.org/mailman/listinfo/int-area
