Configuring IP parameters
TCP/IP configuration parameters (such as IP address, subnet mask, default gateway) can be
configured on the all-in-one in a variety of ways. These values can be configured manually (for
example, through Telnet, the embedded Web server, the arp and ping commands, and HP
management software), or they can be automatically downloaded using DHCP or BOOTP each time
the all-in-one is turned on.
When powered on, a new all-in-one that is unable to retrieve a valid IP address from the network will
automatically assign itself a default IP address. The default IP address will depend on the type of
network to which the all-in-one is connected. On a small private network, a technique called link-local
addressing is used to assign a unique IP address in the range of 169.254.1.0 to 169.254.254.255,
which should be valid. On a large or enterprise network, a temporary address of 192.0.0.192 will be
assigned until it is properly configured for your network. The IP address configured on your all-in-one
may be determined by inspecting the all-in-one Configuration page.
Dynamic Host Configuration Protocol (DHCP)
DHCP allows a group of devices to use a set of IP addresses that are maintained by a DHCP server.
The device or host sends a request to the server, and if an IP address is available, the server
assigns it to that device.
BOOTP
BOOTP is a bootstrap protocol used to download configuration parameters and host information from
a network server. BOOTP uses UDP for its transport. In order for devices to boot and load
configuration information into RAM, they must communicate through the bootstrap protocol BOOTP
as a client with their server.
To configure the all-in-one, the client broadcasts a boot request packet containing at least the
hardware address of the all in one (all-in-one hardware address). The server answers with a boot
reply packet containing the information the all-in-one needs to configure.
