Patent

CA 2651521

A method and system for implementing name challenge enabled zones is described herein. A DNS server receives an update from a client device. If the DNS server hosts an authoritative zone for the update, the DNS server determines whether there is a record for the host name. If so, then the IP address associated with the host name is determined. The IP address is compared to the source address of the client device sending the update. If the IP addresses match, then the update is accepted.

La présente invention concerne un procédé et un système destinés à mettre en oeuvre des zones activées de changement de nom. Un serveur DNS reçoit une mise à jour de la part d'un dispositif client. Si le serveur DNS héberge une zone d'autorité pour la mise à jour, le serveur DNS détermine s'il existe un fichier pour le nom d'hôte. Dans l'affirmative, alors l'adresse IP associée au nom d'hôte est déterminée. L'adresse IP est comparée à l'adresse source du dispositif client envoyant la mise à jour. Si les adresses IP correspondent, alors la mise à jour est acceptée.
