iCIDR v 2.0
iCIDR was designed out of necessity. A personal need to have a simple, easy to use tool for performing CIDR network block math and network masks with complete confidence.
A cornerstone of worldwide 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 CONVERT
CIDR Convert(er) 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).
- E-mail the results anywhere, using the iOS built in mail application
Don’t spend your time calculating the offset with your scientific calculator, just use iCIDR
