Computer Networks | IP Addressing | Question 7

In class B if subnet mask is 255.192.0.0 Total Number of networks than can be joined
(A) 32
(B) 64
(C) 16
(D) None of the Above


Answer: (B)

Explanation: Number of network can be joined is 2^n , n is the number bits borrowed from network bits.
Default Subnet mask 255.255.0.0 .i.e 11111111.11111111.00000000.0000000
Given Subnet mask is 11111111.11000000.00000000.0000000
Number of bits taken from network bits = 6
Number of subnets = 2^6 =64
