Net Calc Pro calculates (as its little brother) various parameters of an IPv4 net. Additionally, it also supports IPv6 networks.

Just enter a valid IP address and the length of the subnet or prefix.

The following values are calculated:

1. •Net Mask
   

2. •Net Address
   

3. •Broadcast Address (IPv4 only)
   

4. •Minimum and Maximum Address
   

5. •Maximum Number of Nodes
   

6. •Maximum Number of possible Subnets
   

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

The following extended functionalities are available:

1. •Conversion from IPv4 to IPv6 and vice versa (if possible)
   

2. •Information about RFC, if the input parameters are following a certain scheme
