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 located on that network. Each IP address can be
divided into two separate parts: the network portion and the
host portion. It is possible for a host to query a server for a
dynamic IP address each time the device boots-up (see the
section "
Dynamic Host Configuration Protocol (DHCP) .")
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.
IP Address: (Network Portion)
Network addresses are managed by an organization in Norfolk,
Virginia recognized as InterNIC. InterNIC has been contracted
by the National Science Foundation to manage the Internet
addresses and domains. Network addresses are distributed to
organizations that are in turn responsible for making sure all
attached devices or hosts on the network are properly
numbered. For more information on the network portion of an
IP address, see "
IP Address Structure and Class " and
" Subnets " later in this appendix.
IP Address: (Host Portion)
Host addresses numerically identify specific network
interfaces on an IP network. Usually a host has only one
network interface; thus, only one IP address. Because no two
devices can share the same number at the same time,
administrators typically maintain address tables to assure
correct assignment of addresses in the host network.
IP Address Structure and Class
An IP address is comprised of 32 bits of information and
divided into 4 sections containing 1 byte each section or 4
bytes total:
xxx.xxx.xxx.xxx
