HP Jetdirect J7949e Administrator's Manual page 33

With link-local addresses, subnetting is not used. The subnet
mask will be 255.255.0.0, and cannot be changed.
Link-local addresses will not route off the local link, and access
to or from the Internet will not be available. The default gateway
address will be the same as the link-local address.
If a duplicate address is sensed, the HP Jetdirect print server
will automatically reassign its address, if necessary, in
accordance with standard link-local addressing methods.
●
On large or enterprise IP networks, a temporary address of
192.0.0.192 will be assigned until it is reconfigured with a valid
address through supported TCP/IP configuration tools. We refer
to this address as Legacy Default IP.
● On mixed-environment networks, the self-assigned default IP
address may be either 169.254/16 or 192.0.0.192. In this case,
you should verify on the Jetdirect configuration page that the
assigned default IP address is as expected.
The IP address configured on your print server may be determined
by inspecting the Jetdirect configuration page for the print server.
See Chapter 9.
Default IP Address Configuration Options
Default IP Parameter Options
A Default IP configuration parameter on the print server controls
how the default IP address is assigned. Whenever the print server
is unable to obtain an IP address during a forced TCP/IP
reconfiguration (for example, when manually configured to use
BOOTP or DHCP), this parameter will determine the default IP
address to use.
When the print server is in a factory-default state, this parameter
is undefined.
If the print server is initially configured with a default IP address
(either a link-local IP address or the legacy default 192.0.0.192 IP
address), the Default IP parameter will be set to either Auto IP or
Legacy Default IP to match.
The Default IP parameter can be changed through a supported
configuration tool, such as Telnet, a Web browser, the printer
control panel, and SNMP management applications.
