OpenIPApi

Bulk IP check

Paste a list of IP addresses — from server logs, a spam report or an export — and we'll email you a full geolocation and threat report for every one of them.

Up to 50 public IPv4 or IPv6 addresses. Duplicates are removed automatically.

One email with the results table — nothing else, no newsletter.

What's in the report?

For every IP: country, city, ISP, and the three anonymization flags (VPN, proxy, Tor) plus a 0–100 threat score. The data comes from the same continuously-updated database that serves our API — not a stale GeoIP dump.

Need more than 50, or need it programmatically?

The batch endpoint of our API handles up to 1,000 IPs per request with the full response schema — abuse contacts, ASN details, connection type and more. The free plan includes 10,000 lookups a month.
