Subnet mask calculator
With subnet mask you can split your network into subnets. Enter your IP address and play with the second netmask until the result matches your need.
This type of notation is also known as CIDR. CIDR (Classless Inter-Domain Routing, sometimes known as supernetting) is a way to allocate and specify the
Internet addresses used in inter-domain routing more flexibly than with the original system of Internet Protocol (IP) address classes.
