subnetting question -yeah another one

Practicing some subnetting and was moving right along until I hit this one.
Sometimes it's like the subnetting "HowTo" just slides out of ear.

Is this right? If so please explain how. Thanks all.

Question: How many subnets and hosts per subnet can you get from the network 10.0.0.0 255.255.240.0?
Answer: 4096 subnets and 4094 hosts

10.0.0.0 255.255.240.0 is the subnet. So its 4096 addresses in the range, 4094 usable host addresses.

So, you are correct.

Yes this is correct. There are 12 bits for the network and 12 bits for the hosts.

amount of networks = 2 to the 12th = 4096
amount of hosts = 2n-2 = 2 to the 12th -2 = 4094

I think what you fail to look at is the ip add this is a class A address so we save the first 8 bits of the mask, the next 12 is your subnet.
