<p>The invention relates to a system and method of communication control. A device (2) is equipped with a program capable of transmitting a DNS request and a control program (1) for intercepting said DNS request. The control program (1) comprises means (11, 12) for communicating with a DNS server (4) to which said DNS request is transmitted and an authorisation server (5). An authorisation request, separate from the DNS request, comprising an identifier (ID) of the user of the device and the domain name, is transmitted to said DNS server (4). The authorisation server (5) returns a response established on the basis of the identifier (ID) of the user of the device and the domain name contained in the authorisation request to the DNS server. Said means (13) for communicating with said transmitting program transmits an IP address defined on the basis of the response of the authorisation server (5) to said program.</p> |
