Setting the IP Address on the Computer (Mac)

Use the information you have prepared through discussions with the network administrator to set the computer's network. If you have already set the network, the settings here are not necessary.
IMPORTANT

In an environment where the computer being used is connected to multiple network devices and the Internet, inappropriate settings will have a large effect on the entire network. For detailed information about the settings, consult your network administrator.

The method introduced here for configuring the network settings applies to the following Mac version. Even with the same version, the operation steps, button names, and screen titles may differ depending on the OS build.
