TCP/IP
Similar to a common language that people use to communicate with each other, TCP/IP (Transmission
Control Protocol/Internet Protocol) is a suite of protocols designed to define the way computers and
other devices communicate with each other over a network.
IP address
Every host (workstation or node) on an IP network requires a unique IP address for each network
interface. This address is a software address that is used to identify both the network and specific hosts
that are located on that network. It is possible for a host to query a server for a dynamic IP address each
time the device boots up (for example, using DHCP and BOOTP).
An IPv4 address contains four bytes of information, divided into sections that each contain one byte.
The IP address has the following format:
xxx.xxx.xxx.xxx
NOTE: When assigning IP addresses, always consult the IP address administrator. Setting the wrong
address can disable other equipment operating on the network or interfere with communications.
Configure IP parameters
IP configuration parameters can be configured manually, or they can be automatically downloaded by
using DHCP or BOOTP each time the product is turned on.
When turned on, a new product that is unable to retrieve a valid IP address from the network
automatically assigns itself a default IP address. On a small private network, a unique IP address in the
range of 169.254.1.0 to 169.254.254.255 is assigned. The IP address for the product is listed on the
product Configuration page and the Network report. See
Control-panel menus on page 9 .
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 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.
The client broadcasts a boot request packet that contains the product hardware address. The server
answers with a boot reply packet that contains the information that the device needs for configuration.
