The domain name system is usually used to translate a host name into an IP address Domain names comprise a hierarchy so that names are unique, yet easy to remember.DNS provides a mapping from names to resources of several types.

Authoritative DNS technology

Give authoritative answers for one or more zones. The master server normally loads the data from a zone file A slave server normally replicates the data from the master via a zone transfer.
