DNS Enabler can set up a fully-functioning Domain Name Server (DNS) on a plain Mac OS X machine. It is designed to allow a user to set up domain name information quickly using a single window, in the fastest time.
DNS Enabler provides the interface to allow users to specify domain name-to-address mappings for machines on the Internet, as well as their aliases or MX records (e.g., which machines act as mail servers for the domain).
Additionally, it allows users to set the other domain and zone information, e.g., Time-To-Live Intervals, that determine how long these information remain valid.
It will automatically generate the named.conf file, the forward mapping files for each domain, the reverse mapping files for each network, and all the resource and reverse pointer records.
