ipcalc is an open-source IP subnet calculator and address validation tool. It can take an IP address and netmask and calculate the resulting broadcast, network, Cisco wildcard mask, and host range.

What is Ipcalc?

ipcalc is an open-source command-line utility used for IP address calculations and validation. It can perform several useful network subnetting tasks such as:

• Convert between IP address, netmask, wildcard mask, Cisco wildcard mask, host range, etc.
• Calculate network information from a IP/netmask, such as network address, broadcast address, subnet mask, host IP range, etc.
• Validate entered IP addresses and netmasks for correct values
• Supports both IPv4 and IPv6 calculations

ipcalc is available on most Linux distributions and Mac OSX as a standard package. It has a simple command-line interface that makes it easy to perform subnetting tasks right from the terminal. The output is colorized for readability. It's a handy utility for network engineers, system administrators, and others who routinely work with IP addresses and subnets.
