1. A method for automatically determining address information and network environment information in an internetwork of networks mutually connectable to each other under a network environment, said internetwork having at least one setting device, said method comprising:

  • (a) managing, in said setting device connected to one of the networks, address information and network environment information used for each device connected to each network to operate under the network environment, the network environment information including information unique to each network, including protocol information;

    (b) sending, from a setting-needed device moved from one of the networks to another network or newly joined to one of the networks, a request message for requesting address information and network environment information to said setting device;

    (c) establishing, in said setting device, a correspondence between a host name of the setting-needed device and a network address of the setting-needed device and sending back a reply message to the setting-needed device from the setting device, the reply message including the address information containing the host name and the network address of the setting-needed device and the network environment information;

    (d) storing, in the setting-needed device, the address information and the network environment information sent from said setting device, so that the setting-needed device can operate under the network environment; and

    (e) reconfiguring the networks of the internetwork based on the information stored at step (d) to accommodate the setting-needed device after being moved from one of the networks to another one of the networks or newly joined to one of the networks, wherein said network environment information includes a domain name of a naming device and a community name of a network management protocol.
