Subnetting Practice Master

I struggle with advanced Subnetting and was waiting for someone to develop an app like this as it challenges what I know ( or what I think I know). I'm so pleased that someone has put clear thought and consideration into this app and it works great on so many levels!

Helpful when you want it to be, and ruthless when you need it to be. Bring a basic understanding of how subnetting works, and this app will help clarify, crystallize and habituate the mechanics in your mind. Like a strong wind will blow out a candle but fuel a fire, this app will bewilder the clueless and make gods of men. Or help a bit.

I greatly appreciate the simplicity within the app. No frills. You are provided a host ipv4 address and a CIDR. You figure out the other computations. There is CIDR and subnetting practice. This app has truly helped me with being able to speed through the subnetting math. The explanations on how correct computations could use some extra detail, but it’s sufficient. Need to learn quick subnetting computation? This is your app. THANK YOU, Enrique! I’d love to see an IPv6 EUI-64 to solicited-node / MAC converter test!

The answer explanations are my favorite. Good little app for learning subnetting.

I was a little skeptical at first because there wasn't enough reviews for this to have a rating in the app store yet. I have to say Im glad I read the other user reviews and then took a chance. This is REALLY helping in assessing my subnetting studies. It is easy to use and very helpful in explaining how to answer the question and come to the correct conclusion. For me it was well worth the cost for such great tool.

Updated app is very good. I really like the WHY button, very helpful. Thanks for fixing it up. I can tell Developer spent a great deal of time on this app. It works smooth and very helpful in learning subnetting. If you are trying to get your CCNA or other Cisco cert, you should purchase this app and practice, practice, practice!

This app was missing the explanation on each question, now it have it 👍👍👍👍

Jeremy Cioara from CBT Nugget subnetting style, pretty nice update now with explanation on each question, well done!

Just love it! This is my fist review ever on itunes after ages of using its apps and this is because you app my friend WORKS!!! using the Jeremy Ciara subnetting method and this app for my subnetting! This app rocks! It even reminded me of wild card masks, which I had completely pulverized in my mind, ha!

This app really makes you think, even in Easy mode. If you can score well in any of the three modes (Easy, Hard, Master) you should be able to easily handle any CCNA subnetting questions.
