# Setting IPv6 Addresses

|  | The IPv6 addresses of the machine can be configured via the Remote UI. Before setting IPv6 addresses, check the IPv4 address settings (Setting IPv4 Address). You need to set the correct IPv4 settings to use IPv6 addresses. The machine can use up to seven of the following IPv6 addresses:

Type | Maximum number available | Description
Link-local address | 1 | An address that is only valid within a subnet or link and cannot be used to communicate with devices beyond a router. A link-local address is automatically set when the IPv6 function of the machine is enabled.
Manual address | 1 | An address that is entered manually. When using this address, specify the prefix length and default router address.
Stateless address | 4 | An address that is generated automatically using the MAC address of the machine and the network prefix that is advertised by the router. Stateless addresses are discarded when the machine is restarted (or turned ON).
Stateful address | 1 | An address obtained from a DHCP server using DHCPv6.

[Use Manual Address]
When you want to manually enter an IPv6 address, select the check box and enter the IP address, prefix length, and default router address in the corresponding text boxes.
[IP Address]
Enter an IPv6 address. You cannot enter an address that starts with "ff" (or multicast address), the address of "0000::0000" (all zeros), or an address that starts with "0:0:0:0:0:ffff" or "0:0:0:0:0:0."
[Prefix Length]
Enter a number that indicates how many bits are available for the network address.
[Default Router Address]
Specify the IPv6 address of the default router as necessary. You cannot enter an address that starts with "ff" (or multicast address), the address of "0000::0000" (all zeros), or an address that starts with "0:0:0:0:0:ffff" or "0:0:0:0:0:0."
[Use DHCPv6]
Select the check box when using a stateful address. When not using DHCPv6, clear the check box.

Perform a hard reset.
Click [Device Control], select [Hard Reset], and then click [Execute].
The settings are enabled after the hard reset is performed.

##### Checking whether the settings are correct Make sure that the Remote UI screen can be displayed with your computer by using the IPv6 address of the machine. Starting Remote UI ##### Selecting settings from the operation panel You can also enable or disable IPv6 addresses from the setting menu of the operation panel. IPv6 Settings ##### If you changed the IP address after installing the printer driver By following the procedure for changing the standard TCP/IP port described in the "Printer Driver Installation Guide", specify the port to use again.
