Limits subnet masks to classes abandoned in the early 1990s. Often leaves out the first subnet from the list of possible subnets. No support because it's free, but there are plenty of free subnet calculators that WILL fix their bugs when reported. If you're using this freebie while deciding if you should pay for any of their other products, consider this an example of their work and a caveat. I'm giving it 1 star because SnapFiles doesn't offer 0 stars as a choice.
