7 BIND 9 is striving for strict compliance with IETF standards. We
8 believe this release of BIND 9 complies with the following RFCs, with
9 the caveats and exceptions listed in the numbered notes below. Note
10 that a number of these RFCs do not have the status of Internet
11 standards but are proposed or draft standards, experimental RFCs,
12 or Best Current Practice (BCP) documents.
47 [1] Queries to zones that have failed to load return SERVFAIL rather
48 than a non-authoritative response. This is considered a feature.
50 [2] CLASS ANY queries are not supported. This is considered a feature.
52 [3] Wildcard records are not supported in DNSSEC secure zones.
54 [4] Servers authoritative for secure zones being resolved by BIND 9
55 must support EDNS0 (RFC2671), and must return all relevant SIGs and
56 NXTs in responses rather than relying on the resolving server to
57 perform separate queries for missing SIGs and NXTs.
59 [5] When receiving a query signed with a SIG(0), the server will only
60 be able to verify the signature if it has the key in its local
61 authoritative data; it will not do recursion or validation to
62 retrieve unknown keys.
