Abstract
A method and device for sending a request (R) from a requesting machine (H) to a domain name server (1, 2, 3). A prior test of the validity of the destination telephone number (NTEL) of the request (R) is executed automatically and locally to the requesting machine (H) relative to a database (BD) local to said requesting machine (H) in order to forward the request (R) from the requesting machine (H) to the domain name server (1, 2, 3) only if its telephone number (NTEL) passes said test.
