IP Address Validator for IPv4 & IPv6

This IP address validator checks whether a string is a properly formatted IPv4 or IPv6 address and classifies it as public, private, or loopback based on standard reserved ranges. It's a practical utility for network engineers, sysadmins, and developers who need to quickly confirm an IP is well-formed before using it in firewall rules, DNS records, or connection strings. Instead of manually checking octet ranges or IPv6 colon groupings, this ipv4 validator and ipv6 validator combo handles the logic instantly and explains the classification in plain terms. It's especially handy for verifying whether an address falls in a private range like 10.0.0.0/8 or 192.168.0.0/16, or whether it's a loopback address like 127.0.0.1 or ::1. Validation runs entirely in your browser with no data sent anywhere - just type or paste an address below to see the result immediately.
