title: How to calculate subnets
body: <p>It's been a while and haven't been able to figure out how I can subnet the below ranges. Could someone help me to subnet these ranges and provide some insight?</p>

  Subnet the 172.16.0.0 address space into 13 subnets.
  Subnet the 192.168.1.0/24 address space into 4 subnets.
