IP Keypad - Subnet Calculator 4+

Nice Real Nice

Easy to use, fast, and this my first app that works smoothly.

Good App Needs Some Additional Features

Overall good but it should include a readout for number of subnets created. That’s important to know if you need to plan the number of network segments. Also a “would like to have” is to be able to switch the display to show the IP and subnet in binary so we can learn from it.

Developer Response ,

Thank you for your review.
My other apps may be helpful for you. ‘Subnet gauge’ has ability to show number of subnets and ‘IP Keypad Pro - Subnet Calc’ has ability to show addresses in binary.

I think it may be better if single app has both ability, so I intend to consider whether to be able to add the ability of ‘Subnet gauge’ to ‘IP Keypad Pro - Subnet Calc’.

Wildcard Mask

I just discovered this app today and I have to say it’s really handy. Suggestions: adding a wildcard mask to the list will make it a 5 star review for me. Great app

Developer Response ,

Thank you for your review. I am very happy that I got a good review from you.
My the other app ‘Subnet Mask’ may be helpful if you would like to know a wildcard mask from a prefix length.

As regards adding a wildcard mask to ‘IP Keypad - Subnet Calculator’, I think I have to consider carefully. A addresses represented by a wildcard mask may contain multiple subnetworks (or multiple networks). On the other hand, this app shows information assuming a single subnetwork (or a single network). For instance, this app shows Number of host addresses, but the value is incorrect if addresses represented by a address and a mask entered in this app contains multiple subnetworks (or multiple networks). This is because network addresses and directed broadcast addresses of each subnetwork (or each network) need to be excluded from number of host addresses.

I am worried that it might cause confusion when this app shows a wildcard mask because this app only assume a single subnetwork (or a single network). I would like to work for this issue if l found good idea to solve this.
