Abstract

L'invention concerne un procédé et un dispositif de sélection d'un serveur de nom de domaine. Le procédé consiste à: lorsqu'il est déterminé qu'un mode courant est un mode de configuration automatique, sélectionner, conformément à un mode stocké de configuration de serveur de nom de domaine, une adresse de serveur de nom de domaine attribuée par un côté réseau pour résolution de nom de domaine; et lorsqu'il est déterminé que le mode courant est un mode de configuration manuel, sélectionner une adresse préconfigurée de serveur de nom de domaine pour résolution de nom de domaine. Selon l'invention, la configuration statique d'une adresse de serveur de nom de domaine par un utilisateur peut être combinée avec une attribution dynamique d'une adresse de serveur de nom de domaine par un réseau, ce qui permet une adaptation souple à divers scénarios d'application dans une application réelle.
