Abstract

La présente invention concerne un procédé, un dispositif et un système d'analyse de nom de domaine. Le procédé d'analyse de nom de domaine consiste : à recevoir une demande d'analyse de nom de domaine qui correspond à une adresse de page web spécifique et est envoyée par un client ; à analyser la demande d'analyse de nom de domaine, de manière à acquérir l'adresse de page web spécifique ; et en prenant l'adresse de page web spécifique en tant que fonction d'extraction, à effectuer une récupération dans un ensemble de relations de mappage entre des adresses IP et des noms de domaine, de manière à acquérir une adresse IP correspondant à l'adresse de la page Web spécifique. Au moyen du procédé décrit dans la présente invention, lorsqu'un fichier de page Web est ouvert par l'intermédiaire d'un navigateur client, différents ports ou chemins sous le même nom de domaine peuvent être définis pour accéder respectivement à une machine désignée, ce qui permet d'obtenir l'effet d'améliorer l'expérience de l'utilisateur.
