CIDR Calculator was designed to streamline CIDR calculations by creating a simple, easy to use tool for performing CIDR network block math and network masks with complete confidence.
A cornerstone of worldwide IPv4 network communications is Classless Inter-Domain Routing, also known as CIDR. CIDR blocks help routers move packets based on a shorthand method of telling another system what IP ranges the devices can route.
The application allows rapid deconstruction and understanding of any valid CIDR block notation.
