  • a Domain Name Server is a system for translating a domain name into an IP address so as to enable access to a specific host belonging to a specific network using only a domain name without requiring that the numerical IP address be memorized in order to access the specific host. That is, an IP address is a numerical address of four bytes (or 6 bytes) separated by periods for respective bytes, such as '147.46.80.205'.
  • a domain name is composed of characters indicating an organization domain, an organization type domain, a region (country) domain, etc., such as 'sis.snu.ac.kr', so that names are more easily understood and memorized than numbers, and thus domain names are widely used when an Internet user accesses a website.
  • This invention relates to a service configured such that, in order to allow Internet users to easily access desired websites, an Internet address represented by a URL is registered as a reference language representation (keyword represented in Hangeul or the like) that can be easily input so as to easily memorize the Internet address, and such that, when a reference language representation (keyword represented in Hangeul or the like) is input into the address box of a web browser, the web browser determines whether the character string input into the address box is a URL or a reference language representation (keyword), transmits the character string to a DNS, and accesses a website corresponding to the URL if it is determined that the input character string is a URL, and the web browser accesses a reference language representation service server, in which a URL or an IP address corresponding to the reference language representation is registered, receives the corresponding URL or IP address, and accesses a website corresponding to the URL or the IP address if it is determined that the input character string is a reference language
  • the prior patent is problematic in that, during a procedure in which a web browser determines whether a character string, input into an address box, is a URL or a reference language representation (keyword), when an English character string and/or '.' are included in the input character string, the input character string is treated as a URL, so that the character string is transmitted to a DNS, and thus a recently popularized Hangeul domain (Hangeul.kr, Hanguel.net, Hangeul.org, etc.) and a multilingual domain (for example: Japanese.jp, etc.) cannot be applied to the service of the prior patent.

Abstract

L'invention concerne un procédé et un système d'accès Internet basé sur DNS par mots-clés. Selon ces procédé et système, si une chaîne de caractères entrée dans le champ adresse d'un navigateur Web (200) est conforme aux règles de syntaxe de noms de domaine, le navigateur Web adresse une requête à un DNS (400) concernant la chaîne de caractères et accède à un site Web correspondant lorsqu'il existe des informations d'adresse IP correspondantes. Le navigateur Web joint un identificateur à la chaîne de caractères d'entrée, adresse une nouvelle requête au DNS concernant la chaîne de caractères d'entrée au moyen de l'identificateur, reçoit l'adresse IP d'un serveur d'accès par mot-clé (500), transmet la chaîne de caractères d'entrée, reçoit une adresse URL ou IP correspondant à la chaîne de caractères d'entrée et accède à un site Web correspondant si une réponse indiquant qu'il n'existe aucune information d'adresse IP correspondante est reçue, que la chaîne de caractères corresponde ou non aux règles de syntaxe de noms de domaine.
