named
Execute the DNS (Dynamic Name Service) server daemon that converts host names to IP addresses and vice versa.
TLDR
Read the default configuration file /etc/named.conf, read any initial data and listen for queries
$ named
Read a custom configuration file
$ named -c [path/to/named.conf]
Use IPv4 or IPv6 only, even if the host machine is capable of utilising other protocols
$ named [-4|-6]
Listen for queries on a specific port instead of the default port 53
$ named -p [port]
Run the server in the foreground and do not daemonize
$ named -f
