That long-expired draft says: A priming query SHOULD use a QNAME of "." and a QTYPE of NS. Davey's question appears to be about implementations that don't seem to do that, but instead just send a first query with RD=1 to a server on configured priming list. Mark Andrews' response was "If you are going to trust them to give you the root NS RRset you can trust them to give you a TLD referral", which seems about right to me. That is, is there really a reason for starting the cache with a query for ". IN NS" instead of just "whatever IN A"? --Paul Hoffman _______________________________________________ dns-operations mailing list dns-operations@lists.dns-oarc.net https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
