摘要

PROBLEM TO BE SOLVED: To provide a network access system, network access method, program and recording medium in which a client user is capable of unconsciously accessing a server present on a network of a different Internet protocol version.

SOLUTION: If a client transmits to a second server a name address of a first server and an Internet protocol version of the network whereon the first server is present, the second server redirects an address of a server of a corresponding network as an IP address, the client discriminates an Internet protocol version based on a display system of the redirected IP address, and a connection destination network is switched based on a result of the discrimination, to access the first server.
