<p>PROBLEM TO BE SOLVED: To provide a name resolver for solving a host name corresponding to plural domain name spaces. SOLUTION: Name servers 11 and 12 and a host 3 are related to a domain name space 10, and name servers 21 and 22 and a host 4 are computers related to a domain name space 20. Based on the host name applied by inquiring it to the name servers 11 and 12, the name resolver of the hosts 1 and 2 retrieves the domain name space 10. When the relevant host name is not found out, by inquiring it to the name servers 21 and 22, the domain name space 20 is retrieved. The hosts 3 and 4 can retrieve only the domain name space 10 or 20.</p> |
