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...

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.
