Abstract:
   This document recommends improved DNS [RFC1034] [RFC1035] resolver
   behavior with respect to the processing of Name Server (NS) resource
   record sets (RRset) during iterative resolution.  When following a
   referral response from an authoritative server to a child zone, DNS
   resolvers should explicitly query the authoritative NS RRset at the
   apex of the child zone and cache this in preference to the NS RRset
   on the parent side of the zone cut.  Resolvers should also
   periodically revalidate the child delegation by re-quering the parent
   zone at the expiration of the TTL of the parent side NS RRset.
