Network Installation
6. In the Stateless Addresses area:
a. The Link-Local Address is automatically populated.
This is a network address which is intended only for use in a local data link layer network, and
not routed beyond that network. Link-local addresses are often used for network address
auto-configuration where no external source of network addressing information is available.
The printer's IPv6 Link-local address is automatically generated, and displayed here. Link-
local addresses always begin with "fe80".
b. Check the [Use Router Supplied Prefixes] checkbox if router advertisements are used.
A router-supplied prefix is the 64-bit (sub-) network address. If routers are present, they will
periodically send Router Advertisement packets containing address prefixes. These prefixes
determine what sort of auto configuration can be done by the device. Select this setting to
use Router Supplied Prefixes. When enabled, Global Addresses associated with this device are
displayed. If there are no routers on the network, this setting can be disabled.
c. The [Global Addresses] will display any global addresses associated with the device. Global
addresses are equivalent to public IPv4 addresses. They are globally routable and reachable
on the IPv6 internet.
7. The device performs auto-address DHCP configuration every time it powers up. This is used for
neighbour discovery and address resolution on the local IPv6 subnet.
However, you can choose to use manual configuration, automatic configuration or a combination
of automatic and manual configuration.
Default Dynamic Host Configuration Protocol (DHCP) Settings area:
a. Select one of the following options:
• Use DHCP as directed by a router - this option is fully automatic. The DHCPv6 Address
will be obtained and displayed on the screen.
• Always Enable DHCP for address assignment and other configuration data - this
option is fully automatic. The DHCPv6 Address will be obtained and displayed on the
screen.
• Always Enable DHCP for other configuration data only - this is the semi-automatic
configuration. The DHCPv6 Address will be obtained and displayed on the page.
• Never use DHCP - when this option is selected, you must configure the Manual Address
Options and DNS separately.
b. If you select either [Use DHCP as directed by a router] or [Always Enable DHCP for address
assignment and other configuration data] you have the option to enable the release of
DHCPv6 Address at Power Down. This option instructs the printer to send a DHCP release
message to the router when the device is powering-down. This releases the current DHCP
configuration and discards the printer's IP Address configuration.
To select this option check the [Release DHCPv6 Address at Power Down] checkbox for
DHCPv6 Address.
8. In the DNS Configuration area:
a. Enter an IP Address for the [Preferred DNS Server]. Enter an IP Address for [Alternate DNS
Server 1] and [Alternate DNS Server 2].
b. Check the [Prefer IPv6 Address over IPv4] checkbox to enable this option.
By default, the printer will prefer an IPv4 address over IPv6 address if both are enabled. For
example, when querying the DNS, the printer will normally use the IPv4 address if an IPv6
address is also provided. By selecting this checkbox, this will change the preference to IPv6.
