This option is used to specify maximum time to cache negative
answers. Default is 3 hrs. This value should not exceed 7 days and
will be truncated to 7 days if a longer time period is specified.
• transfer-source
This option specifies the IPv4 address to use for inbound zone
updates, which is also the source address to use for refresh queries
and forwarded dynamic updates. If not set, it defaults to a
system-controlled value which will usually be the address of the
interface “closest to” the remote end.
• request-ixfr
This option is used to determine whether the local server, acting as a
master, will respond with an incremental zone transfer when the
given remote server, a slave, requests it. If set to yes, incremental
transfer will be provided whenever possible. If set to no, all transfers
to the remote server will be non-incremental. If not set, the value of
the provide-ixfr option in the global options block is used as
default.
• provide-ixfr
This option is used to determine whether the local server, acting as a
slave will request incremental zone transfers from the given remote
server, a master. If not set, the value of the request-ixfr option in the
global options block is used as default. This option is used to allow
incremental zone transfers for the requests to the master server.

This option is used to specify the maximum number of recursive
lookups the servers will perform on behalf of clients. Default is 1000.
• tcp-clients
This option is used to specify the maximum number of TCP
connections a server will accept. Default is 100.
• tkey-domain
This option is used to specify the domain name that is appended to

exchange, it may or may not specify the desired name for the key. If
present, the name of the shared key will be "client specified part" +
