Warren. In both cases receiving a query with either a option or a qname encoding ids it is a indication that the IP address or the clients behind the IP address have the trust anchor configured. You may receive a option without the recursive server actually validating.
As far as I can see both options provide the same information. Mark _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
