Overview

IP Address Details (ipinfo.io) returns geolocation and network information for any IP address, including city, region, country, ISP, and organization. It is one of the most reliable IP lookup APIs and works without authentication for basic usage. Paid plans unlock higher rate limits and additional fields.

💡

Beginner Tip

Without a token you are limited to 50,000 requests/month — sufficient for most projects. Append /json to any IP address URL like https://ipinfo.io/8.8.8.8/json for a clean JSON response.

Common Errors & Troubleshooting

429 Too Many Requests You have exceeded the free tier limit of 50,000 requests per month.
✓ Sign up for a free API token to get a higher quota, or add the token as a query parameter: ?token=YOUR_TOKEN.
Bogon IP in response The IP is a private/reserved range like 192.168.x.x or 10.x.x.x.
✓ Only look up public IP addresses. For testing, use a public IP like 1.1.1.1.
Missing city or region fields Some IPs do not have precise geolocation data beyond the country level.
✓ Always check for null or missing fields and provide fallback values in your application.
