CA 2642027

An embodiment is directed to a method for selectively routing a DNS request in which a DNS request to translate a domain name is received from a local client device. The DNS request is directed to a remote DNS server on a remote network. A link status to the remote network is identified. If the link status indicates that a connection to the remote network is not possible, the DNS request is routed to a locally embedded DNS server. If the link status indicates that a connection to the remote network is possible, the DNS request is routed to the remote DNS server on the remote network.

La présente invention concerne un procédé pour le routage sélectif d'une requête DNS dans lequel une requête DNS pour traduire un nom de domaine est reçue depuis un dispositif de client local. La requête DNS est dirigée vers un serveur distant DNS sur un réseau distant. Un statut de lien au réseau distant est identifié. Si le statut de lien indique qu'une connexion au réseau distant n'est pas possible, la requête DNS est routée vers un serveur DNS intégré localement. Si le statut de lien indique qu'une connexion au réseau distant est possible, la requête DNS est routée vers le serveur DNS distant sur le réseau distant.
