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::

1. •Net Mask
   

2. •Net Address
   

3. •Broadcast Address
   

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) 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.

Interface is simple yet straight to the point. Accurate results. Great for any network engineer or system network configuration person.

Nice small tool By tprfct on Jul 01, 2009

Version 1.2.1

Very helpful application for busy sysadmin. Responds quickly to netmask change. Shows IP address in hex which is useful for setting PXE boot configurations. Allows to erase entered IP address in one tap instead of doing it digit by digit as some other IP calculators do.
