IPify

Overview

IPify is the simplest possible IP-address API: it tells you your public IP address in plain text or JSON. No registration, no key, no limits for basic use. It’s the canonical “what’s my IP” endpoint for server checks, client-side diagnostics, and status pages.

Note: geo.ipify.org (the URL in the listing) is the paid geolocation product — the free IP-lookup API lives at api.ipify.org and is documented at ipify.org.

Quick Start

Plain text (works in any shell):

curl "https://api.ipify.org"

JSON (verified live):

curl "https://api.ipify.org?format=json"

{"ip":"210.61.187.110"}

IPv6 (via the v6 endpoint):

curl "https://api64.ipify.org?format=json"

Authentication

None — keyless, registration-free.

• CORS is enabled (Access-Control-Allow-Origin: * verified), so browser clients work.
• HTTPS is supported — always use it.
• api64.ipify.org returns your IP in both IPv4 and IPv6 environments.
