•Determines which part of an IP address is the network field and which part is the host field

•Follow these steps to determine the subnet mask:

–1. Express the subnetwork IP address in binary form.

–2. Replace the network and subnet portion of the address with all 1s.

–3. Replace the host portion of the address with all 0s.

–4. Convert the binary expression back to dotted-decimal notation.
