An IP range is a contiguous set of IP addresses from a start address to an end address. For example, 192.168.1.0 to 192.168.1.255 contains 256 addresses.

Does this support IPv6?

This calculator supports IPv4 addresses only. IPv6 ranges involve 128-bit numbers that require different handling.

How is the total calculated?

Each IPv4 address is converted to a 32-bit number. The total is simply (end - start + 1).
