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 device on an IP network requires a unique IP address. This address can be manually set by the
user or can be obtained automatically, depending on the available network services.
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 product sends a request to the server, and if an IP address is available, the server assigns it to that
product.
BOOTP
BOOTP is a bootstrap protocol used to download configuration parameters and host information from
a network server.
The product 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 product needs for configuration.
Subnets
When an IP network address for a particular network class is assigned to an organization, no provision
is made for more than one network being present at that location. Local network administrators use
subnets to partition a network into several different subnetworks. Splitting a network into subnets can
result in better performance and improved use of limited network address space.
