Paste or upload
Add a short list of public IPs by pasting text or uploading a simple CSV.
Bulk Lookup
Bulk IP Lookup
Look up multiple public IP addresses in one workflow. Paste a list or upload a CSV, validate automatically, then review ISP and location details with optional exports.
Paste comma-separated IPv4 or IPv6 addresses, or upload a CSV with a single column headed ip. Up to 50 valid IPs per batch. Lookups run one at a time in your browser.
Need to check more than 50 IP addresses? Please Contact us for higher-volume lookups and custom solutions.

How it works
From paste to export in four clear steps
Bulk Lookup is built for short lists of public addresses. Validate first, look up in sequence, then review or export the results.
Validate the list
IPinfoLabs checks formatting and separates valid public addresses from entries that cannot be processed.
Process lookups
Valid addresses are looked up in sequence so you can follow progress without juggling one-off searches.
Review and export
Inspect ISP and location details in the results table, then export a report if you need to keep a record.
Best use cases
Where bulk IP lookup helps most
Use it when you need the same network context across many addresses without switching tools for every IP.
Network administration
Review multiple public endpoints in one pass when checking infrastructure or vendor connections.
Security investigations
Gather public IP context for short lists of addresses during triage or follow-up checks.
Log analysis
Look up batches of public addresses pulled from logs without repeating the same single-IP workflow.
IT support
Help users faster by validating several related public IPs in the same session.
Infrastructure auditing
Collect consistent network details across a short inventory of public addresses.
Research
Explore public IP metadata across multiple targets while keeping the workflow simple and exportable.
Benefits
Bulk Lookup benefits
Designed for practical workflows: less repetition, clearer results, and exports you can keep with your notes.
Saves time
Replace repeated single lookups with one short bulk workflow.
Handles multiple IPs
Process up to 50 public addresses in a single bulk session.
Consistent reporting
Review and export results in a shared format that is easy to compare.
Faster troubleshooting
Keep related addresses together so patterns are easier to spot.
Easy workflow
Paste, validate, process, and export without creating an account.
Good to know
IP types and accuracy
A short reference for what Bulk Lookup accepts and how to interpret the results.
IPv4 and IPv6
Bulk Lookup accepts public IPv4 and IPv6 addresses in the same list when they are valid.
Public vs private
Private, reserved, or malformed addresses are flagged during validation and are not treated as public lookup targets.
Accuracy notes
Results reflect available public network data and can vary by provider, routing, or recent changes.
FAQ
Bulk Lookup questions
Quick answers about limits, private addresses, storage, and access.
How many IPs can I look up at once?
You can process up to 50 public IP addresses in a single bulk lookup session.
Can I look up private IPs?
No. Bulk Lookup is intended for public addresses. Private or reserved ranges are marked invalid during validation.
Are my IP lists stored on a server?
The bulk workflow is designed for client-side use in your browser session. Export locally if you need to keep a record.
Do I need to register?
No registration is required to paste a list, run validation, process lookups, or export results.
