Network Fundamentals – Chapter 6
Objectives
Explain the structure IP addressing and demonstrate the ability to convert between 8-bit binary and decimal numbers.
Given an IPv4 address, classify by type and describe how it is used in the network.
Explain how addresses are assigned to networks by ISPs and within networks by administrators.
Determine the network portion of the host address and explain the role of the subnet mask in dividing networks.
