IP2Location — Free IP Address Geolocation API (No Key)

TL;DR

IP2Location provides a free IP geolocation API that transforms any IP address into rich geographic and network data: country, region, city, latitude/longitude, ZIP code, ISP, domain, timezone, and connection type. The free tier supports basic lookups with reasonable rate limits. Just pass an IP as a query parameter and get structured JSON back. Ideal for localization, analytics enrichment, fraud detection, and regional content targeting.

  });

4. Python — Bulk Lookup

import requests

ips = ['8.8.8.8', '1.1.1.1', '208.67.222.222']
for ip in ips:
