Hi Elvis, I think the number of sub-assignments is something that can be very different in different cases and we may end-up with a new case that will not fit the policy. My rational to /64 is that actual IETF work direction is very consistent with a /64 to be used in a single interface (a host having VMs, for example) and I think this match very well what it may be the difference between PI and PA (while we keep it). https://datatracker.ietf.org/doc/draft-ietf-v6ops-unique-ipv6-prefix-per-hos...

Furthermore, if we want to be restrictive on this, we could add a limitation that the maximum sub-assignment can be /64. how about... if we want to be restrictive - instead of limiting the size of the prefix, we limit the number of sub-assignments one can make from a PI? elvis ********************************************** IPv4 is over Are you ready for the new Internet ? http://www.consulintel.es The IPv6 Company This electronic message contains information which may be privileged or confidential.
