Abstract

Dans ses modes de réalisation, la présente invention se rapporte à un procédé et à un équipement de locaux d'abonné pour la redirection d'un message de système de noms de domaine (DNS) basée sur un réseau IPv6 (Internet-Protocol-Version-6). Le procédé selon l'invention consiste : à recevoir un message de demande de DNS en provenance d'un terminal d'utilisateur (101) ; s'il est déterminé que l'adresse du site de destination du message de demande de DNS est une adresse de site local, le procédé consiste alors à obtenir l'adresse DNS globale correspondant à l'adresse du site local (102) ; et transmettre le message de demande de DNS à l'adresse DNS globale (103). La présente invention se rapporte également à un équipement de locaux d'abonné qui permet d'améliorer l'efficacité de la mise en œuvre de la technologie de redirection de messages DNS ainsi que la gestion des adresses.
