Net Calc

Net Calc calculates various parameters of an IPv4 network. Just enter a valid IP address and the length of the subnet.

The following values are calculated::

-Net Mask
-Net Address
-Broadcast Address
-Minimum and Maximum Address of a Node
-Maximum Number of Nodes in the Net
-Maximum Number of possible Subnets

If one input parameter (IP address and/or subnet) is changed, all other parameters will be re-calculated.

If the input parameters follow a certain scheme, a textual description and the defining RFC are displayed.
