Type an IPv4 or IPv6 address to validate it, see its canonical normalized form, and its classification. Runs entirely in your browser.
Classification covers the classic well-known ranges (RFC 1918 private space, RFC 4193 unique-local, loopback, link-local, multicast, unspecified, IPv4 broadcast) — narrower than the full IANA special-purpose address registry.
curl -sS -X POST https://devops.majbase.com/ip-validator/api -H "Content-Type: application/json" -d '{"ip":"2001:db8::1"}'Returns {"valid", "version", "normalized", "type"}, or {"valid": false, "error": "..."}.
