Subnet Calc

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.

This is unusable. Can’t type anything without auto-directing to the App Store. Apple needs to ban this from the App Store!!!

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

Great

I like the app. It's bugged where it displays the subnet type and hosts in the wrong field. Also it would be nice if there was a button to show the next usable subnet.
