aSubnet 4+

I have been looking for a subnet calculator for some time. But this isn't quite it. you only have 1 way to determine subnets and that is via an IP Range.

This program would be fantastic if:-
You could determine your ip range from the amount of hosts you need or networks.
Able to reverse calculate an ip address from a subnet mask. listing all the possible networks
Listing al broadcasts anD starting and finish ip Ranges.

If these where implemented i would gladly pay for this product

A subnet calculator is certainly something I use regularly, and so to be able to have it as an iPhone app is a great idea. However this needs a little more functionality before it becomes useful.
This tool can tell you the network and broadcast address for an IP address based on the subnet mask, as well as how many available host addresses in that range.
What would be useful is to be able to calculate the mask necessary to accomodate a certain number of hosts, or the available network addresses genarated by subnetting a given address, for example. Hopefully these are features planned for updates to this tool

This isn't that bad, it does the basic day-to-day stuff that I use but lacks a few choice features, such as the range of hosts for the chosen subnet which I find especially useful. I hope there is an upgrade coming. With a bit of work this could be one of the best tools for techies avaliable on the app store.
