IPinfo

Overview

IPinfo resolves IP addresses to rich geolocation, network, and ASN data. The basic lookup is keyless with rate limits (verified live); a free token raises limits and unlocks company/privacy data.

Quick Start

Your IP (verified live):

curl "https://ipinfo.io/json"

{
  "ip": "210.61.187.110",
  "city": "Kaohsiung",
  "region": "Kaohsiung",
  "country": "TW",
  "loc": "22.6148,120.3139",
  "org": "AS3462 Data Communication Business Group",
  "timezone": "Asia/Taipei"
}

Specific IP:

curl "https://ipinfo.io/8.8.8.8/json"

With a token:

curl "https://ipinfo.io/8.8.8.8/json?token=YOUR_TOKEN"

Authentication

• Anonymous: works but rate-limited (verified).
• Free token: register at ipinfo.io → dashboard → token (50k requests/month).
• Send it as the token query parameter or Authorization: Bearer header.

Rate Limits & Notes

• Anonymous: limited (roughly 50k/month per IP too, but throttled); free token: 50,000 requests/month.
• Fields: city, region, country, loc (lat,lng), org (ASN + org), timezone, postal.
• Paid tiers add company, privacy (VPN/proxy detection), and abuse data.
• CORS-enabled for browser use.
