Paste a list of addresses from a log file, a firewall export or a spreadsheet. Each entry is validated, normalised and looked up against our own datasets: the announced route and origin AS from the BGP table, the registry and registration country from the RIR files, and DB-IP’s location estimate.
Nothing in a bulk lookup goes to a third party, and none of it is stored: the list is sent once to our server, answered from local indexes in a few milliseconds and forgotten. Live sources (reverse DNS, RDAP) are not queried in bulk; open a single address for those.
Up to 100 entries per request. Duplicates are reported once, and invalid entries are listed with the line they came from.
常见问题
Why is there a limit?
To keep the service fair for everyone and to stop it being used to map networks wholesale. For larger jobs, use the JSON API from a script with the published rate limits.
Is the location accurate?
It is an estimate from DB-IP Lite. It is usually right about the country and often wrong about the city. Registry country is a separate fact: where the block's holder is registered.
Can I download the results?
Yes, as JSON or CSV, generated in your browser from the results on the page.
