HP PN1050 - Manual (Page 14)

ENWW TCP/IP Configuration 14
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 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
through the projector’s on-screen Help menu that the assigned default IP
address is as expected.
The IP address configured on your projector server can be found on the
projector’s on-screen Help menu.
Default IP Address Configuration Options
Default IP Parameter
A Default IP configuration parameter on the projector server controls how the
default IP address is assigned. Whenever the 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 server is in a factory-default state, this parameter is undefined.
If the 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 a Web browser and SNMP management applications.
