Abstract

PROBLEM TO BE SOLVED: To recognize, convert and issue the 1-byte code and 2-byte code of a domain name. SOLUTION: A conventional DNS does not retrieve a host name using something other than alphanumeric symbols such as the 2-byte code. By the system, the host names of Japanese and Chinese, etc., can not be used. In a DNS system, by converting a retrieved host name to the alphanumeric symbol corresponding to a conversion table and delivering it to this DNS, retrieval is performed by a normal alphanumeric host name on the side of the DNS.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION DNS for searching for a host name containing a 2-byte code.

[0002]

2. Description of the Related Art Conventional DNS does not search for a host name using a character other than an alphanumeric symbol such as a 2-byte code. In this method, host names such as Japanese and Chinese could not be used.

[0003]

In the conventional DNS, host names other than alphanumeric symbols cannot be searched.

[0004]

[Means for solving the problem] The searched host name is
The DNS is characterized in that it can be converted to an alphanumeric symbol in accordance with a conversion table and passed to the DNS, so that the DNS can be searched with a normal alphanumeric host name.

[0005]

Embodiments of the present invention will be described below. First, a host name of an arbitrary code is passed from a client to a DNS server. After receiving this, the server checks the data against the conversion table. If there is data in the conversion table, the host name received from the client is replaced with the host name using only the alphanumeric code described in the conversion table. The IP address corresponding to the designated alphanumeric code is resolved by a normal DNS search and a response is sent to the client.

[0006]

According to the present invention, a host name including an arbitrary character code such as Japanese, Chinese, etc., in addition to English, can be used as a DN.
S makes it possible to solve the problem.
