Abstract

La présente invention concerne le domaine des communications Internet, ainsi qu'un procédé et un dispositif d'accès à un nom de domaine. Le procédé comprend : un équipement d'utilisateur détermine que l'équipement d'utilisateur se déplace d'une première zone d'emplacement vers une seconde zone d'emplacement ; l'équipement d'utilisateur définit une première adresse de protocole Internet (IP) dans un cache de nom de domaine devant être invalide et envoie un premier message de demande de résolution de nom de domaine à un serveur de système de nom de domaine (DNS) ; l'équipement d'utilisateur reçoit un premier message de réponse de résolution de nom de domaine, le premier message de réponse de résolution de nom de domaine portant une seconde adresse IP correspondant à un nom de domaine ; l'équipement d'utilisateur ajoute la seconde adresse IP au cache de nom de domaine ; l'équipement d'utilisateur accède au nom de domaine au moyen de la seconde adresse IP. En déclenchant la mise à jour d'un cache de nom de domaine lorsqu'il est déterminé qu'un équipement d'utilisateur se déplace entre des zones d'emplacement et en accédant à un nom de domaine au moyen d'une adresse IP mise à jour, la présente invention peut mettre en œuvre l'accès à un serveur optimal correspondant à un nom de domaine par l'équipement d'utilisateur et présente un retard court et une efficacité de communication élevée.
