Subnetting divides one network into smaller ones, for example a /16 for a site into /24s for each floor or VLAN. Every extra prefix bit doubles the number of subnets and halves their size.
Pick the network and the new prefix length; the list shows each subnet with its first and last address.
How many subnets do I get?
Two to the power of the difference in prefix length. A /16 split into /24s gives 2^8 = 256 subnets of 256 addresses each.
