What is bulk IP lookup?
Bulk IP lookup adds network context to a short list of addresses in one pass. Instead of checking entries individually, you can paste addresses from server logs, support tickets, incident notes or troubleshooting data and receive normalized country, ASN and organization fields in a table.
When is bulk lookup useful?
Website administrators can use it to understand a small group of unfamiliar addresses, developers can enrich diagnostic data, and security teams can quickly identify whether several events come from the same ASN or network type. CSV export makes the result easier to compare offline.
What advanced enrichment adds
When advanced intelligence is configured, the tool can add selected VPN, proxy, Tor and risk fields. These are classifications rather than identity data. A shared hosting network, VPN exit or mobile carrier can represent many unrelated users.
Why the input size is deliberately limited
The browser processes lookups sequentially to respect third-party service limits and avoid turning a free interactive utility into an unrestricted scraping endpoint. The current limit is intended for human-scale investigations rather than large datasets.
Bulk geolocation is not attribution
Country, city, ASN and reputation fields describe the network around an address. They do not prove who generated a request. For incident response, preserve timestamps and your own application logs and use IP enrichment as supporting context.
Need repeated automated lookups?
For integrations or recurring workloads, use the documented JSON API rather than automating the browser tool. The API has its own rate limits and returns a normalized result intended for software use.
