Week 5
Lab 8 Exercise 8.1.1
Class A networks are defined as those that use only the first byte (also called an octet) of the address as the network identifier. The rest of the address is considered the host identifier. In this type of network, the number of possible networks is much smaller than the number of hosts that can be connected to the same network. If the IP address in Figure 8-1 belongs to a class A network, what is the network ID and what is the host ID? Network ID is 110 and the Host ID is 10.10.1 What are the binary values of the host ID and the network ID? Network ID is 01101110 Host ID is 00001010.00001010.00000001
Lab Exercise 8.1.2
Table 8-1
Class range of First Byte (Octet) in Decimal Network ID host ID possible Networks possible hosts per Network
A 0-127 A BCD 128 16,777,216
B 128-191 AB CD 16384 65,536
c 192-223 a b c D 2,097,152 256
Use your textbook and the Internet to complete Table 8-1. Why is the number of possible networks for each class not equal to 2 raised to the power of the number of bits used for the network ID?
The number isn’t equal to 2 raised to the power of the number of bits because you always have to take away 2 from the network for the network and broadcast address
