# IP Calculator

The calculator is JavaScript based and refreshes as you type. It will calculate the
- IP Address
- Network mask
- Wildcard
- Network address
- Broadcast address
- First Host IP
- Last Host IP Number of Hosts in the network

Both IPv4 and IPv6 are supported

The IP Calculator is added to the views of
- Aggregate
- Prefix
- IP Address

In addition the plugin adds the ability to visualize and share the subnetting of a prefix into smaller subnets
