THE INTERNET REGISTRATION DESK
Look up a public IP’s registered network. Keep the range, registry and dates in context.
YOUR QUERY
WHERE THE QUERY GOES
The submitted IP goes through our server to an official Regional Internet Registry. No lookup runs until you request it.
Have a hostname? Resolve it first with NAME2IP, then look up one returned address here.
THE RESULT
READY WHEN YOU ARE
Submit an IP to see the registered range, network name, handle, registry, events and notices returned by the source.
Registration is not personal identity, precise geolocation or proof of who sent traffic.
Includes the queried IP and public record details. Review before sharing.
READ THE SIGNAL
Network, not person. A record describes registered address space. It does not identify the individual using an IP.
Dates, not traffic history. Registry events describe the record, not login times or observed attacks.
Source, not guesswork. Follow the official record when you need more detail than this summary displays.

curl ipwhois.infoA bare command returns your source IP and one newline. It does not trigger a registration lookup. The JSON API provides a separate, explicit RDAP endpoint.

No. Registered address space may be used by a provider, its customers, a cloud platform or a VPN. The returned record is not proof of a device owner or user.
A registry country field is not a live location measurement. It may not describe where a particular device or connection is located.
Private and other special-purpose ranges are outside this tool’s public-registration lookup scope. The same private address can be reused on many networks.
Registries differ in what they publish. Missing data is labeled “Not provided,” not guessed. Successful summaries may be reused for up to ten minutes; the original fetch time stays visible.
No. It is a registry record status, not a malware, spam, trust or reachability assessment. IPWHOIS does not issue reputation scores.
