What will we Learn from chapter 6?

The structure of IP addressing and demonstrate the ability to
convert between 8-bit binary and decimal numbers.

For an IPv4 address, how to classify by type and describe how it
is used in the network.

How IP addresses are assigned to networks by ISPs, and within
networks by administrators.

To determine the network portion of the host address and explain
the role of the subnet mask in dividing networks.

Given IPv4 addressing information and design criteria, You will
learn how to calculate the appropriate addressing components.

How to use common testing utilities to verify and test network
connectivity and operational status of the IP protocol stack on a
host.
