This read-create integer sets whether the resolver sends this Sbelt name server iterative queries with the RD bit off, recursive queries with the RD bit on, or both, controlling how much resolution work is delegated to that server. An administrator configures this based on whether the target server is a full recursive resolver or an authoritative-only server that expects iterative queries. For example, when pointing this entry at an ISP's recursive DNS server, an admin would set this OID to recursive so the RD bit is set on outgoing queries.
