TCP/IP Overview 133

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. The network address

is a four-byte address although some bytes may be expressed

as zeros.

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.
