You have a class B network 172.16.0.0. You use a 11 bits for subnetting. Which of the following is a correct range of Ip addresses that belong to the same network.
a. 255.255.8.1 to 255.255.14.254
b. 255.255.255.9 to 255.255.255.14
c. 255.255.17.1 to 255.255.22.254
d. 255.255.17.0 to 255.255.22.255
Answer / indu
C
Explanation:
If you are using 11 bits for subnetting, you have 5 Netowrk Bits and 11 Node bits
From the subnetting formulas above:
M=5 N=11
The first range = 255.255.X.1 to 255.255.Y.254
where X = 2^(N-8)+1 and Y= 2^(N-8+1)-2
For the next ranges, just add 2^(N-8) at each end of the range
The first range = 255.255.9.1 to 255.255.14.254
2^(N-8) = 2^3 = 8
The second range = 255.255.17.1 to 255.255.22.254
so on and so forth.

You try "ping server1" and you get "unknown host server1" . Why ?
Choose three reasons why the networking industry uses a layered model: * It facilitates systematic troubleshooting * It allows changes in one layer to occur without changing other layers * It allows changes to occur in all layers when changing one protocol * It clarifies how to do it rather than what general function to be done * It clarifies what general function is to be done rather than how to do it
