IP addresses at random as long as each one is unique. However, connecting a private network to the

Internet requires using registered IP addresses to avoid duplication.

The four groups of numbers (octets) are used to identify a particular network and host on that network.

The InterNIC assigns Internet addresses as Class A, Class B, or Class C. Class A supports 16

million hosts on each of 127 networks. Class B supports 65,000 hosts on each of 16,000 networks.

Class C supports 254 hosts on each of 2 million networks. Due to the large increase in access to the

Internet, new classless schemes are gradually replacing the system based on classes.

UDP (User Datagram Protocol)

An Internet Standard transport layer protocol. It is a connectionless protocol that adds a level of

reliability and multiplexing to IP.
