OK, I'll bite. Never, and never (in nearly 20 years). Although we in effect have IPv4 PI as being an older university we came online when getting an old Class B was easy, before IP allocations were made from the NREN space. We have renumbered our IPv6 networking as part of experimental/research work (and would from that experience certainly say fully automated renumbering is not possible today), but that was just an academic (and very interesting) exercise. If IPv6 PI were available to us we'd use it because it costs us no extra to do so. -- Tim _______________________________________________ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf
