# ifconfig

Use the "ifconfig" command to view and configure TCP/IP (IP address, subnet mask, broadcast address, default gateway address) for the printer.

View settings

`msh> ifconfig`

IPv4 configuration

`msh> ifconfig "interface_name" "address"`

- If you did not enter an interface name, it is automatically set to the Ethernet interface.

- wlan can be specified only when the IEEE 802.11 interface is installed.

Interface name | Interface configured
--- | ---
ether | Ethernet interface
wlan | IEEE 802.11 interface

The following explains how to configure an IPv4 address 192.168.15.16 on the Ethernet interface.

`msh> ifconfig ether 192.168.15.16`

IPv6 configuration

`msh> ifconfig ether inet6 "address" "prefixlen"`

The following explains how to configure an IPv6 address to 2001:DB8::100 with prefix length 64 on the Ethernet interface.

`msh> ifconfig ether inet6 2001:DB8::100 64`

Netmask configuration

`msh> ifconfig "interface_name" netmask "address"`

The following explains how to configure a subnet mask 255.255.255.0 on the Ethernet interface.

`msh> ifconfig ether netmask 255.255.255.0`

Broadcast address configuration

`msh> ifconfig "interface_name" broadcast "address"`

Changing the interface

`msh> ifconfig "interface" up`

- When using the optional IEEE 802.11 interface unit, you can specify either Ethernet or IEEE 802.11 interface.

- To get the above addresses, contact your network administrator.

- Use the default configuration if you cannot obtain setting addresses.

- The IP address, subnet mask and broadcast address are the same as that for the Ethernet interface and IEEE 802.11 interface.

- TCP/IP configuration is the same for both the Ethernet and IEEE 802.11 interface. If interfaces are changed, the new interface inherits the configuration.

- Use "0x" as the initial two letters of a hexadecimal address.
