This turns out to be a Well Known Bad Idea (WKBI). Most PTR checks look up the name to be sure there's a matching forward (AAAA in this case) record, and ignore them if there isn't. You can't do that with wildcard PTRs unless you have some way of serving 2^64 AAAA records in a single response. R's, John PS to the literal minded: yes, I know that's impossible. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
