Extended DNS Error message EDE 20 (Not Authoritative) is now sent when client request recursion (RD) but the server has recursion disabled. RFC 8914 mention EDE 20 should also be returned if the client doesn't have the RD bit set (and recursion is needed) but it doesn't apply for BIND as BIND would try to resolve from the "deepest" referral in AUTHORITY section. For example, if the client asks for "www.isc.org/A" but the server only knows the root domain, it will returns NOERROR but no answer for "www.isc.og/A", just the list of other servers to ask. |
