Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. If the first bits of the first octet are '1111' what type of address is it?
Private Use Class A
Class E (11110000--11111111 binary)
To send messages to all hosts on the network at the same time.
The network address is first followed by 0's. examples: Class A network address: 115.0.0.0 - Class B network address: 154.90.0.0 - Class C network address: 221.65.244.0

The Host address on the local network?
Private Use Class A
Used by routers to specify the 'default' route. Generic value reduces the number of routing table entries. Some older routers use this address as a broadcast address.

3. What is the IP address range for Class B?
128-191 (10000000--10111111 binary)
The last octet is 255. (Verify)
255.0.0.0
Routers connected to the Internet typically filter messages within these ranges and prevent them from being propagated to the Internet.
