Here is another one that has stumped me from subnettingquestions.com

Question: How many subnets and hosts per subnet can you get from the network 10.0.0.0/20?

Answer:
4096 subnets and 4094 hosts




If converting over to binary, this is the result:

00001010.00000000.00000000.00000000

11111111.11111111.11110000.00000000


I orginally took all of the 1 values and tried to use that to get the number of subnets, but that number is way to high.

Once I got the answer, they only used the 1 values from the 2nd and 3rd octect.

I'm confused on not using any of the values from the 1st octect and not sure.

thanks
