IP address API for developers

Need your public IP inside a script, a server setup, or an app? whatismyipadd answers with just the address when you request it from a command-line tool, so there's nothing to parse.

Endpoints

Example JSON

{
  "ip": "203.0.113.42",
  "version": "IPv4",
  "city": "Los Angeles",
  "region": "California",
  "country": "US",
  "timezone": "America/Los_Angeles",
  "asn": 64500,
  "isp": "Example Internet"
}

Using it in code

# Python
import urllib.request
ip = urllib.request.urlopen("https://whatismyipadd.com/ip").read().decode().strip()

// JavaScript
const { ip } = await (await fetch("https://whatismyipadd.com/json")).json();

The JSON endpoint allows requests from any website (CORS is enabled). To force IPv4 or IPv6, use curl -4 or curl -6.

Fair use

The API is free for personal and small projects. Please don't call it more than once a minute from automated jobs; cache the result instead. We may limit traffic that harms the service for others.
