Classifies an IPv4 or IPv6 address: family, canonical form, and whether it is public, private (RFC 1918 or unique local), loopback, link-local, carrier-grade NAT, multicast, documentation, or reserved, including IPv4-mapped IPv6. With no input over HTTP, returns the caller's own public IP and country. Useful for validating network input and filtering internal addresses. Not charged for an invalid address.
