Great app. Easy to use and does what it says. Much more useful than others I've seen. Wish I could export but hey. Ps lot of people says it crashes on 32 subnet because there isn't really a 32 subnet and this crashes because I guess it doesn't know how to handle that. Anyways great app and do add an export feature.
this is fine for calculation, also the application is light enough, I hope the people will keep the skill of manual subnetting calculation :-) But It would be more than excellent if we can add additional subnetting while keeping the last one on the screen.
when i first learned subnetting there weren't smart phone or apps. It was all long hand. I decided to revisit some subnet training after not needing to for many years and I am so glad I found this app. I still like to understand the manual technique but this sure speeds up the process. Thanks!
Very good and simple for calculating Subnets. Easy to use and clear. Excellent..... ( Just a quick side note... as other users have issues with app crashing out when a '/32' mask is entered, I've had no problems ( Samsung S6 Edge ) )
What a fantastic app! The unexpected option it has is helping you plan your networks, which is huge to a newb network architect. 100% will recommend to others. Thank you for a great product.
Quick and easy to use. Must have if you're in the field without network connectivity and don't feel like calculating it yourself!
Thank you very much ... The app is just wonderful. Just one bug I found that is while calculating vlsm network of the phone is rotated , the networks added gets deleted
Showing decimal, binary, and CIDR on same screen at same time is wonderful! It does close when placing CIDR 32, though. I guess no biggie. Good job! Thank You!
easy to use, handy to have. Makes subnetting quick and very helpful in diagnosing connection issues as they relate to improper use of IP addressing
Good app with a bug In VLSM calculator, it should prevent user from entering a network with a host nomber larger than the orginal prefix is providing, yet it does allow the user to do so, and manipulate the prefix length (That shouldn't be done) to provides a sufficient number of hosts.
Great app! So far 100% correct subnetting. Easy to use and comprehensive- no need to use any other IP calculator when you have this tool.
Wonderful subnet calculator. Breaks down a specified network and mask into network and broadcast addresses, first and last useable host, and total hosts, and it includes an easy to use VLSM calculator. Just wish it had an IPv6 calculator, too.
Great app but it doesn't seem optimized for the newer android versions and sized of screens! The app screen is smaller than my screen
From all the entertainment, gaming, story telling, workout, social or trendings apps in the play store. This is probably the best mobile app I have ever seen!
This app is great especially when you're dealing with computer networks that requires subnetting. Life saver!
Super easy to use. Does great job at subnetting. Highly recommended.
Quick and easy. Without aggressive ads. Tried at least 5 different apps - this one looks best!
Fantastic app, by default it shows no ads, but they can be turned on to support the developer
Very intuitive to use and with lots of functionality, definitely recommended.
great app but I can't read the last numbers of the host addresses because it goes off the screen on oneplus 8 pro.
Makes subnetting look more easy to understand without all the math it saves alot of time.
App does everything it needs to do and nothing more. Great app that helps me when my brain can't!
This is a very useful app! I use a few times a month and it's perfect for anyone in the IT industry.
Excellent - does EXACTLY what I need so I'll be deleting other similar apps.
It's really helpful. Really help to calculate subnet mask for me thanks for the developer recommended
This app is still crashing. I must stick with the "Easy IP Subnet Calculator".
I really happy to use this app, it's answer gives accurate and quick i suggest this app is very useful for network engineer.
good app... it could also have options to display list of all IP ranges under a subnet
App crashes with a /32. You need to add some more error handling.
This is something I could have used back in the 1960's. We spent quit a lot of time calculating these. So far it has been 100% correct. There are quite a few "blocks" of addresses that we set for "system use only". A lot has changed during the years, but not having to write a "quick ditty" to make sure your addresses are correct is worth more than 5 stars. Thank you so much...
