IP2Location

Overview

IP2Location’s web service resolves an IP address to location data: country, region, city, latitude/longitude, ZIP, timezone, ISP, and (on paid tiers) proxy/VPN detection, threat data, and more. A free key lets you query the lite dataset.

Quick Start

Look up an IP (replace YOUR_KEY):

curl "https://api.ip2location.io/?key=YOUR_KEY&ip=8.8.8.8"

No ip parameter returns the caller’s own IP info:

curl "https://api.ip2location.io/?key=YOUR_KEY"

Authentication

• Register at ip2location.io — a free key (100 requests/month) is provided.
• Send it as the key query parameter.

Rate Limits & Notes

• Free tier: 100 requests/month (2 locations/s rate) — the lite dataset (country/region/city/coordinates).
• Paid tiers add proxy/VPN detection, threat intelligence, ISP, and higher limits.
• Responses are JSON with fields like country_code, city_name, latitude, longitude, time_zone, asn.
• They also sell offline databases (IP2Location LITE is free) if you need bulk lookup without an API.

FAQ

Is IP2Location free? There’s a free tier (100 requests/month) with the lite dataset.

How accurate is it? City-level accuracy varies by IP; it’s geolocation, not exact physical location.

Can I get VPN/proxy detection for free? No — that’s on paid tiers.
