Unobtrusive - Four tabs--four tasks. This calculator is great for doing the task at hand, and presents the information clearly. However, I think there is a little too much whitespace, especially in the CIDR tab. As a CCNA student, it's a great tool while I try to wrap my head around subnetting, while not getting left behind during lectures.

Good - Does what I need it to do for IPv4. However, please add support for IPv4 multicast subnetting. Furthermore, please allow coping from the fields themselves. For instance I want to copy the subnet ID out. It aggrivates me that I can not do that.
