What is a Class A?
Frst Octet 1-126 Purpose Unicast (large networks)
What is a Class B?
Frst Octet 128-191 Purpose Unicast (medium sized networks)
What is a Class C?
Frst Octet 192-223 Purpose Unicast (small networks)
What is a Class D?
Frst Octet 224-239
Purpose Multicast
What is a Class E?
Frst Octet 240-255
Purpose Experimental
True or False
The addresses in the same network have the same values in the network part.
True
True or False
The address in the same network have different values in the host part.
True
What is the formula to calculate the number of host addresses per Class A, B, or C network?
2^H -2
Where H is the number of Host bits
What are valid network numbers for Class A
1.0.0.0 - 126.0.0.0
What are valid network numbers for Class B
128.0.0.0 - 191.255.0.0
What are valid network numbers for Class C
192.0.0.0 - 223.255.255.0
How many total networks does a Class A have?
2^7-2 = 126
How many total networks does a Class B have?
2^14 = 16,384
How many total networks does a Class C have?
2^21 = 2,097,152
How many hosts does a Class A network have?
2^24 -2
