By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values. Inverse netmasks are recognized. If you omit the netmask ipcalc uses the default netmask for the class of your network. Look at the space between the bits of the addresses: The bits before it are the network part of the address, the bits after it are the host part.

You can see two simple facts: In a network address all host bits are zero, in a broadcast address they are all set.

The act of dividing a network into at least two separate networks is called subnetting, and routers are devices that allow traffic exchange between subnetworks, serving as a physical boundary.

IPv4 is the most common network addressing architecture used, though the use of IPv6 has been growing since An IP address is comprised of a network number routing prefix and a rest field host identifier. A rest field is an identifier that is specific to a given host or network interface.
