Domain Name System

Domain Name System (often indicated with DNS) is a service used for the resolution of names of host in IP addresses and viceversa. The service is realized through a database distributed, constituted from serveur DNS.

Name DNS denotes also the protocol that regulated the operation of the service, the programs that implements it, the serveur on which these they turn, with of this serveur that they cooperate in order to supply the service.

Names DNS, or "names of I dominate", are one of the characteristics more visible than Internet.

There is confusion with respect to the definition of the acronym: the S often comes interpreted like service, but the correct definition is system.

The operation to convert a name in an address is said resolution DNS, to convert an IP address in name is said inverse resolution.
