Analytic method for variant domain name in domain name system (DNS)

The invention relates to an analytic method for a variant domain name in a domain name system (DNS). According to the method, in an acquisition step, an authoritative server guides a received domain name query request to a domain name converter; in a judgment step, the domain name converter judges whether a domain name corresponding to the domain name query request is an international domain name or not, if the judgment result is yes, a first converting step is performed, if not, the domain name converter returns information about inexistence of the domain name corresponding to the domain name query request to the authoritative server; in the first converting step, the domain name converter converts the domain name corresponding to the domain name query request into a standard domain name of a standard coded format; in a first analytic step, the domain name converter compares the standard domain name with a registration information table set therein, if the standard domain name exists in the registration information table, a skip instruction is returned to a query host sending the domain name query request, so that the query host skips to a website corresponding to the standard domain name, if the standard domain name does not exist in the registration information table, a second converting step is performed; and in the second converting step, the domain name converter converts the standard domain name into a recommended body domain name.
