how to find number of bit requirement for number of network , like 8 networks requires 3 bits
number in bit for Subnetting
You must understand Binary conversion up to 8 bits to fully understand why this works but the quick and easy way is to understand how binary is represented.
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^7 = 128
2^8 = 256
You can see how tis works, in our CCNA show, or in our legacy library the CCENT show.
