Hello. I'm teaching myself about subnetting. The book I'm using is saying something I don't understand, and I'm awful at math and computers in general.
00|000000 (0)
01|000000 (64)
10|000000 (128)
11|000000 (192)
Where are the other 2 subnets the formula says should exist? Moreover, the equation 2 to the power of 3 = 8. I'm completely lost.
Any help would be appreciated.
But I see only 4 possible permutations.start with a beginning subnet mask and extend the subnet extension until you have the number of subnets you need. The formula for determining how many subnets you create is 2 to the power of y, where y is the number of bits you add to the subnet mask.
If you move the network ID extension over one, its only a single digit, 2 to the power of 1.
lets take /24 and subnet it down to /26. Extending the network ID by two digits creates four new network IDs, 2 to the power of 3 = 6.
