ipv4 Subnet Calculator
An easy to use, simple subnet calculator that takes the hassle out of the many intricacies involved with the ipv4 subnet system. This tool will allow you to accurately subnet different class networks as well as calculate the number of hosts allowed.
The subnet calculator is as flexible as possible, allowing for a multitude of ways to automatically advance to the next field with the intentions of allowing for multiple keyboard layouts. After entering in an octet you can hit any of the keys to advance fields. Also, after three digits entered, the field will advance automatically.
- The period key
- The Space key
- The
* key
- The # key
You can quickly and easily retrieve the network range a host device to effectively determine if your device resides within your given network configuration.
The binary tab illustrates some of the patterns that can help the beginner start to learn the subnet process.
Quickly and easily e-mail or save various network configurations for reference later.
Please feel free to contact me with any features/updates you would like to see added to this tool.

Actually gives me a total list of EACH usable network and their range. Most others didn't.
Super application for subnetting and very simple to use. It has that value.
Missing /31 and anything above /8. App is incomplete
Not supported Android v12
The best for lazy guys
It works and do the right calculation.
Really Very Useful Application.
The best
Does not show dotted decimal subnet mask under "decimal" tab anymore, just wildcard mask. This is one of the best ipv4 subnet calculators I've run across.
The subnet calculations are perfect but once we go back it won't ask for confirmation and exit directly and all our result is gone. Please include such option
Gets the job done quite well. Could use some minor UI and organizational tuning, but as it is now it's much better than the average app...
It can take wrong ip but can make subnets of it
It was a life saver for me during my exam, installed it during the exam and corrected my mistakes!
Fantastic! Calculation of subnets range is most excellent ability of this app.
very nice app, very benificial, helps me during my work
It saves me a kot of work lol
Working on my CCNA studies. This is exactly what I was looking for. Thanks.
This application is great for anyone starting out in networking or is not mathamatically saavy enough to make quick binary calcs
Simple and easy to use.
Ease of use and understand
Love it.. very useful app(tool)
Saves a lot of time and calculations
Okay so if I choose an address like 182.68.50.0 that's class B. I want to subnet it to the cidr of 26 but cannot because it stops 23. I should be able to choose the cidr from 1 to 32.
I would like to have the usable networks listed instead of just all the networks to prevent mistakes. For instance in class c /27 there are 8 networks but 6 usable. Besides that great app
Great app. Well organized and exceptionally usefull. Best out of 3 previous that i have installed/uninstalled. Still looking for the purchase version free of ads.
The only subnet app I've seen to figure out that removing the "." Between octets for ip entry speeds up the process tenfold! Nice to see someone thinking about usability.. thank you. +1 to a purchasable ad free version
Amazing app which is very accurate and helpful. Highly recommended.
Easy to use, has all the info I need
👍 very useful, easy to use. the interface of app would be more friendlier. other apps doesnot show all the subnets in a list, just shows the first subnet details.but this app does.
