Not should, MUST be authoritative. It MUST return responses with "aa" set in the flags to non-reqursive queries for names within the delegated namespace or it MUST return a referral to nameservers which in turn are authoritative for the sub-delegated namespace. Note: queries for the SOA record at the delegation MUST return the SOA record with "aa" set. There is no horizontal delegation in the DNS. > What happens if the nameserver to which we delegate the subdomain is a > NON-AUTHORITATIVE nameserver (eg., cache-only name server ). ?
