Bulk IP Intelligence

What is a Bulk GeoIP lookup?

A Bulk GeoIP lookup enriches many public IP addresses in one batch instead of checking them individually. BulkGeoIP extracts addresses from lists, CSV data, or raw server logs, removes duplicates, and returns a structured report you can search, map, and export.

1. Paste or upload

Enter mixed IPv4 and IPv6 addresses, paste unedited access logs, or select a TXT, LOG, or CSV file up to 5 MB. File contents are read locally; only extracted IP addresses are submitted for lookup.

2. Analyze up to 1,000 IPs

The tool combines approximate location, ISP, organization, ASN, reverse DNS, WHOIS, and available proxy or hosting signals into one searchable result set.

3. Investigate and export

Sort and filter the table, inspect geographic patterns on the map, star important rows, then download the current results as CSV or JSON for further analysis.

Designed for real network workflows

Use Bulk GeoIP for Nginx or Apache log analysis, incident response, suspicious-login review, abuse triage, firewall exports, traffic research, and IP-list enrichment. Country and network ownership data are generally more dependable than city coordinates; GeoIP is an estimate and should never be treated as a person’s exact physical location.
