Classful Network Architecture
Why you have not subtract 2 from NIDs of B and C class?
Because he already have eliminated the fixed bits from couting the total network ID i.e:
For Class B:
fixed bits- 2(1,0)
total network bits- 16
total manipulative bits = 16-2
So, Total Network ID's = 214
Similarly for class C, total network id's = 221.
becuase he mentioned that the two NID adress were eliminated only for class A network, because the first and last is used for noIP/invalidIP and loopback adress respectively
Range of class D is 224-239.
is class B range from 1-126 or from 1-125. In last video you said it was from 1-125 and in the above it is said as 1-126?
