Taken from Wikipedia.
The system of domain names, in inglese Domain Name System (often referred to by DNS), is a system used for the resolution of names of network nodes (in inglese host) into IP addresses and vice versa. The service is realized by a distributed database, consists of the DNS server.

I server DNS, however, can also be set for block content. A kind of external filter to the computer usable for example for the parental control. By setting the DNS “filter” directly on the router (if the router is configured to act as a DNS server) we will be able to filter at once all the connections of the devices connected to that router. The condition for this to happen is that the devices have connected as a DNS server to the IP of the router.

ADSL providers usually have the DNS servers, on which convey the traffic of its customers for the resolution of the host.

Over the years the service was then enriched for example with the possibility of monitoring its connection, it is possible to block access to certain sites, can be used for example in schools to block social networks. All additional services that can only be activated after you have registered.
