Question: How many subnets and hosts can you get from the network 172.20.0.0/20?

Answer: 16 subnets and 4094 hosts

My Answer was 15 Subnets and 4094 hosts? - How is the answer 16??

On the 3rd Octet the binary is 11110000 which means 4 bits are borrowed for the network ID and 4 plus the remainin octed 8 is used for the host ID

4 = 15 subnets

12 - 4096 (subtract 2 for the broadcase and network address)

How did they get 16??

Thanks

Michael
