Default IP Address Will Be Assigned
A default IP address will be assigned if the factory-default methods fail, or if the print server has just
been re-configured by an administrator to use a server-based method (such as BOOTP or DHCP)
and it fails.
If a default IP address is assigned, the address will depend on the network to which the print server
is connected. The print server senses broadcast packets on the network to determine the appropriate
default IP settings:
■ On small private networks that adhere to automated, standards-based IP address assignments,
the print server uses a link-local addressing technique to assign a unique IP address. Link-local
addressing may be referenced as Auto IP. The IP address assigned will be in the range of
169.254.1.0 to 169.254.254.255 (commonly referenced as 169.254/16), and should be valid.
However, it can be further modified for your network using supported TCP/IP configuration tools
if necessary.
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
re-configured 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
HP Jetdirect Configuration Page.
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 re-
configuration (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.
