subnetting question

[carl_townshend]

Hi all, whats the easiest way of working this out ?

How many subnets are gained by subnetting 172.17.32.0/20 into multiple /28 subnets?

[viyuan700]

172.17.32.0/20 have 4094 hosts.

You are borrowing 8 bits to subnet further in /28

2 power 8= 256.

Now you have 256 more /28 subnets each having 14 host

e.g

172.17.32.0

172.17.32.16

etc
