The following DNS related RFC have been obsoleted

RFC2537 (Obsoleted by 3110)

RFC3152 (Obsoleted by 3596)

[1] Queries to zones that have failed to load return SERVFAIL rather

than a non-authoritative response. This is considered a feature.

[2] CLASS ANY queries are not supported. This is considered a feature.

[3] Wildcard records are not supported in DNSSEC secure zones.

[4] Servers authoritative for secure zones being resolved by BIND 9

must support EDNS0 (RFC2671), and must return all relevant SIGs and

NXTs in responses rather than relying on the resolving server to

perform separate queries for missing SIGs and NXTs.

[5] When receiving a query signed with a SIG(0), the server will only

be able to verify the signature if it has the key in its local

authoritative data; it will not do recursion or validation to

retrieve unknown keys.

[6] Section 4 is ignored.

[7] Requires --with-idn to enable entry of IDN labels within dig,

host and nslookup at compile time. ACE labels are supported

everywhere with or without --with-idn.
