Subnetting Practice Master

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!

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.
