IP Calculator
IP Calculator displays information about an IP address or an IP address range, like subnet-mask, CIDR notation and different notations of the address and the address range.
Address ranges can be entered in CIDR notation (e.g., "198.51.100.1/24") or separated by a hyphen (e.g., "198.51.100.1 - 198.51.100.255").
More information about IPv4 and IPv6 addresses, as well as various terms, is available on the page IP Addresses.
