Description:

CIDR Calculator was designed out of a desire 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. Now, if you’re looking at this tool, you most likely know more about CIDR than I can possibly cover here, so I’ll focus on the unique features of this Application:


CIDR Calculator is a simple to use tool that allows rapid deconstruction and understanding of any valid CIDR block notation.



For example. You’ve received a block of IP’s from your ISP. Maybe they are add-ons to your existing network. Perhaps you are deploying a completely new network. When you look at the provisioning worksheet and see the notation 17.251.200.70/25 you will want to know what IPs are part of that range. Instead of trying to do perform the 32-bit math in your head, or on a calculator, why not just use this handy tool? If you with a simple push of a button you’d have known:



* The true starting IP address of the block: 17.251.200.70

* The top, or end of the IP block: 17.251.200.127

* The decimal equivalent of both the starting and ending IP ranges. Useful in only a few situations, but when you need it, you really need it. (In this case they are 301713408 and 301713535 respectively).



Don’t spend your time calculating the offset with your scientific calculator, just use CIDR Calculator.

No cut n' paste support - It does what it says, no question about that. But as a tool it is hampered by lack of support for cut n' paste. Typos are the bane of working with IP addresses!
