Free IP Lookup
Look up any IPv4 or IPv6 address: city, ISP, ASN, BGP prefix, RPKI validity, PeeringDB, connection type, and fraud-risk signals.
# free & rate-limited · no signup · live results from the same engine as the API
Since the engine is the same one the API runs, a key does not buy you a better answer. It buys volume, bulk jobs and a signed receipt.
Three quick steps
Enter an IP
Paste any IPv4 or IPv6 address.
Live lookup runs
We resolve geo, ISP, BGP, RPKI, and risk signals.

Geolocation
Country, region, and city resolution.
ISP, ASN, BGP, RPKI
The autonomous system, advertised prefix, RPKI validity, and PeeringDB role the engine already returns.
Connection type
Residential, datacenter, or hosting.
IPv4 and IPv6
Same engine for both. Bogon v6 coverage is still being hardened.

FAQ
Is this IP lookup tool free?
Yes. Guests get 5 lookups a minute and 50 a day, no signup. A free account has 200 credits a month, no card, and core validations cost 1 credit each.
How accurate are the results?
The free tool runs the same engine as the API, so what you see here is what an integration returns. Where we cannot determine something we say so rather than guessing — a confident wrong answer is worse than an honest gap.
Can I use this in bulk or via API?
Yes. Paste 20 numbers with no account, or sign in and clean 100 a month on the free plan. Paid plans take longer lists, CSV jobs, webhooks and higher rate limits, from $3.16 per 1,000 core lookups.
Can I paste a list of numbers here?
This page is one IP at a time. For a list of phone numbers use the clean-call-list tool. For many IPs, use the API or a bulk job.
