About IP Address Validation

This tool validates both IPv4 and IPv6 addresses according to Internet standards. IPv4 addresses consist of four decimal numbers (0-255) separated by dots. IPv6 addresses consist of eight groups of four hexadecimal digits separated by colons.

The validator checks for correct format, valid ranges, and identifies special IP addresses (like private, loopback, or multicast).
