If set, only allow these comma separated netmasks to recurse
Authoritative zones can transmit a TTL value that is lower than that specified in the parent zone. This is called a
delegation inconsistency. To follow RFC 2181 paragraphs 5.2 and 5.4 to the letter, enable this feature. This will mean a slight deterioration of performance, and it will not solve any problems, but does make the recursor more standards compliant. Not recommended unless you have to tick an
RFC 2181 compliant
box. Off by default.
Comma separated list of
pairs. Zones read from these files are served authoritatively. Example: auth-zones= ds9a.nl=/var/zones/ds9a.nl, powerdns.com=/var/zones/powerdns.com. Available since 3.1.

Which domains we only accept delegations from
Where to read new entropy from, defaults to /dev/urandom.
If set, this flag will export the host names and IP addresses mentioned in /etc/hosts. Available since 3.1.
If set, fork the daemon for possible double performance
Comma separated list of

If set, load root hints from this file
IP addresses to listen on, separated by spaces or commas

If set, maximum number of entries in the main cache
maximum number of seconds to keep a negative cached entry in memory
Maximum number of simultaneous TCP clients
If set, maximum number of TCP sessions per client (IP address)
Source IP address for sending queries
Send out local IPv6 queries from this address. Disabled by default, which also disables outgoing IPv6 support. A useful setting is
Suppress logging of questions and answers

On by default, this makes the server authoritatively aware of: 10.in-addr.arpa, 168.192.in-addr.arpa and 16-31.172.in-addr.arpa, which saves load on the AS112 servers. Individual parts of these zones can still be loaded or forwarded.
If set, change group id to this gid for more security
If set, change user id to this uid for more security
If set, only use a single socket for outgoing queries

If non-zero, assume spoofing after this many near misses
