# Setting IP v. 6

This section describes the procedure for setting IP v. 6.
Specify the settings for IP v. 6 using the Remote UI after specifying the settings for IP v. 4.

IMPORTANT
IPSec encryption (Security Architecture for Internet Protocol) is not supported for LBP7660Cdn.

NOTE
###### About the IP v. 6 address This printer can have up to seven IP v. 6 addresses of the following types. (Only one address can be registered manually.) IP v. 6 communication allows you to use multiple IP v. 6 addresses simultaneously.
Type | Registrable Number | Overview
Link-Local Address | 1 | A link local address is an IPv6 address that is generated automatically using the specific prefix (information indicating to which network the machine belongs) "fe80::" and an interface identifier generated from the MAC address of the printer. Because this address is valid only within the same prefix, it cannot traverse the router. One link-local address is specified for this printer whenever IP v. 6 is being used.
Manual Address | 0 to 1 | A manual address is a fixed address entered manually. By setting the IP address manually, you can specify the prefix length and the default router address.
Stateless Address | 0 to 4 | A stateless address is a temporary IPv6 address that is automatically generated using the prefix included in the RA (Router Advertisement) that is notified from the router and the printer's MAC address. If the created IPv6 addresses do not overlap on the network, they may be allocated as the printer's IP address.
Stateful Address | 0 to 1 | You can obtain a stateful address from the DHCP server using DHCP v. 6.

1
Start the Remote UI, and then log in as Administrator.
"Starting the Remote UI"
2
Click [Settings/Registration].
3
Select [Network] from the [Preferences] menu.
4
Click [TCP/IP Settings].
5
Click [Edit...] under [IPv6 Settings].
6
Select the [Use IPv6] check box.
7
Specify the stateless address.
Check the [Use Stateless Address] check box when using a stateless address.

NOTE
###### Stateless Address Retention After the [Use Stateless Address] check box is selected and the printer is restarted, the stateless address is displayed automatically. This stateless address is discarded when the printer is turned OFF.

8
If you want to use a manual address, specify the following settings.
If you do not want to use a manual address, proceed to Step 9.

(1) | Select the [Use Manual Address] check box.
(2) | Enter [IP Address].
(3) | Enter [Prefix Length].
(4) | Enter [Default Router Address] as needed.

IMPORTANT
###### Addresses which cannot be entered in [IP Address] and [Default Router Address] An address which starts with "ff" (multicast address) An address which starts with "0:0:"

9
Specify DHCP v. 6.
When using the stateful address, select the [Use DHCPv6] check box.
10
If you want to use the DNS server, specify the following settings.
If you do not want to use the DNS server, proceed to Step 11.
You can specify the following [IPv6 Settings].

(1) | Enter the IP address of the primary DNS server in [Primary DNS Server Address].
(2) | Enter the IP address of the secondary DNS server in [Secondary DNS Server Address].
(3) | Set [Host Name] and [Domain Name]. Select the [Use IPv4 Host/Domain Names] check box to use the same host name and domain name as IPv4.After the printer is restarted, the host name and domain name set by IPv4 are set automatically. When using a host name and domain name that are different from IPv4, enter [Host Name] and [Domain Name]. You can enter up to 47 characters.
Example of [Domain Name] entry: | "example.com"

11
If you want to use DNS Dynamic Update, specify the following settings.
If you do not want to use the DNS server, proceed to Step 12.

(1) | Select the [DNS Dynamic Update] check box.
| Using the DNS Dynamic Update function, by registering the [Host Name] and [Domain Name] to the DNS server, the printer's IP address can be used without being fixed.
(2) | Set whether to register the IPv6 address to the DNS server during DNS dynamic updates. If you select the [Register Manual Address] check box, a manual address is registered to the DNS server. If you select the [Register Stateful Address] check box, a stateful address is registered to the DNS server. If you select the [Register Stateless Address] check box, a stateless address is registered to the DNS server.

IMPORTANT
###### DNS Dynamic Update DNS Dynamic Update is a function that adds the IP address of the device and the names specified as the host name and domain name to the DNS server automatically. This function can be used in the environment in which a Dynamic DNS server is being used. ###### When using the DNS Dynamic Update function You need to set the IP address, host name, and domain name of the DNS server.
