This is a summary of the implementation status of the various named.conf

options in BIND 9.

Legend:

Yes Implemented in this release.

No Not implemented, may be implemented in a later release.

Obsolete Obsolete, not applicable to BIND 9, or just evil.

Will not be implemented.

* New in BIND 9.

+ The option is now always enabled.

- The option is now always disabled.

% The default value has changed since BIND 8.

@ Semantics of certain pathological address match lists, in

particular those involving double negation, have changed.

The new semantics are generally safer. IPv6 addresses

are supported, but the predefined ACLs "localhost" and

"localnets" match IPv4 addresses only.

# BIND 9 accepts both LF and CRLF as end-of-line markers.
