Subnet Calc is a subnet / ip calculator designed to help network administrators who need to remember details about the various subnets which they administer. You can select an IP and a subnet in CIDR notation and Subnet Calc will tell you all the details about the subnet, including its class and even whether or not the IP is in the loopback / private ranges.

There is also a PRO version called Subnet Calc Pro. Be sure to check it out for more advanced features such as an organiser and the ability to find a subnet based upon a given set of IPs.

Good app. Ok interface. Cannot export data.

This is a good basic subnet calculator. It does not use the iPhone's real estate very well. Most of the information that you need to see is below the bottom of the screen. You need to scroll down to see it. The app should allow you to view only the data that concerns you.

It also cannot export the data. That would be handy.

Very nice app

This is a very nice app that's easy to use and you can't beat the price. The ability to save networks is a nice feature as well. The only thing it's missing is the ability to list the max number of hosts and networks. But that's pretty minor. Keep up the nice work
