Setting IPv4 Addresses

The machine's IPv4 address can either be assigned automatically using DHCP or entered manually.
By default, the IPv4 address is set automatically when connected to a wired or wireless LAN, but you can set it or change it manually according to your usage environment and purpose.
This section describes how to configure the settings using the operation panel.
You can also set the IPv4 address using Remote UI from a computer after it has been set on the machine. Managing the Machine from a Computer (Remote UI)
