For the given subnet mask 255.255.255.224 , Find the number of subnets in each class.
sir in question no. of subnet for class A is 2^19 its correct but some times its use no.of subnets in class A = (2^19) -2 . so sir which one use...or both
I think it should use 219-2 since the two host id is used fordifferent purpose
New routers allow SIDs having all 0's and all 1's . So no need to subtract 2.
According to new convention , be it classful or classless , we take it as 2n only , as evident from previous gate questions on this particular topic also..
so i follow........if numerical type question ----> then its 2^n
