we will never know, because every v6 end system will have a ptr, either naturally, or machine-generated for it, because v6 providers will not want their rank-and-file v6 endsystems to be excluded from important activities such as transmitting e-mail. the operational advantage of not having ptr's for rank and file end systems is much easier to explain, except to v6 endsystem providers. -- P Vixie _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
