max-cache-ttl rangetime(0-68y5w3h14m7s) default = 1w
Sets the maximum amount of time that you want the DNS server
to retain cached information. Default is 604800s (1w).
max-dns-packets int default = 500
Specifies the maximum number of packets that dns server will
handle concurrently. DNS server will drop inbound packets if this
limit is reached.
max-negcache-ttl rangetime(0-68y5w3h14m7s) default = 60m
Sets an upper limit on the number of seconds a DNS server
maintains negative cache entries. Default is 3600s (1h).
A server generates these cache entries after querying another
name server and receiving an authoritative reply stating the
requested records do not exist.
max-udp-payload-size rangeint(512-4096) default = 4096
Specifies the sender's maximum UDP payload size, which is
defined as the number of octets of the largest UDP packet
that can be handled by a requestor (See RFC2671).
mem-cache-size rangeint(200-4194303) default = 50000
Indicates the size, in kilobytes, of the in-memory record cache.
minimal-responses bool default = false
Controls whether the DNS server omits or includes records from
the authority and data sections of query responses when these
records are not required. Enabling this attribute may improve
query performance such as when the DNS server is configured as
a caching server.
neg-cache-ttl rangetime(0-68y5w3h14m7s) default = 10m
Indicates how long information learned from other name
servers about non-existent names or data should be cached.
no-fetch-glue bool default = enabled
