Hi, The only openly published standard for a policy implementing resolver of which I am aware is that under the direction of Paul Vixie, formerly of ISC. That standard is Response Policy Zones (RPZ).
I believe that the most recent version is at: https://kb.isc.org/getAttach/21/AA-00512/rpz.txt However, one would be best to check with ISC to confirm that this is the latest.

That would be super. Good question, and no. "Policy-based" and "policy-implementing" are those kind of terms we hear bandied about in operator circles but not written about in RFCs because it is supposedly outside the purview of the IETF. If someone has a reasonable reference we can point to, that would be great. --Paul Hoffman _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
