  Correct Answer: C



IP addresses are written using decimal numbers separated by decimal points. This is called dotted decimal notation of expressing IP addresses.
The different classes of IP addresses is as below:

Class Format Leading Bits Network address Range Max.# of networks

B N.N.H.H 10 128 - 191 16,384 
C N.N.N.H 110 192 - 223 2,097,152 

Network address of all zeros means "This network or segment".
Network address of all 1s means " all networks", same as hexadecimal of all Fs.
Network number 127 is reserved for loopback tests.
