|Expansion of the network had to ensure compatibility with the existing address space and the Internet Protocol (IP) packet structure, and avoid the renumbering of the existing networks. The solution was to expand the definition of the network number field to include more bits, allowing more networks to be designated, each potentially having fewer hosts.|

|For class B n/w port is 2 byte and no of host port is 2 byte = 16 bits.
No of n/w = 2^14.
No of nodes = 2^16-2.

|I am not getting this calculation. Can someone explain it clearly?|
|Niraj Singh said: (Apr 10, 2017)|
|No of nodes/host= 2^n - 2( where n is number of host bit).
eg. For class A, 11111111 00000000 00000000 00000000;
Here, host bit is total number of 0, i.e 24.
In each IpV4, we have 4 set of decimal number is separated by (.), which mean four octets of a binary digit (0 & 1).
Number of network= 2^(n-m (or 2)).

|What are Classes of a network? Please explain.|
|Kumar Shanu said: (Sep 1, 2018)|
|There are generally 5 classes of network, A, B, C, D, E and generally we people using class C network.|

|Based on IPv4
The IP length is 32 bits( 4 Bytes).
Based on the first Byte we can say the type of class.
class A =1-126.
In this 0 & 127 is used for special purpose;
0.0.0.0 -----> Not Possible,
127.0.0.0 -----> Multi casting.
