IP Lookup
See your public IP and look up registration data for any IP
What is IP Lookup?
This IP lookup tool shows your current public IP along with the country, city, and time zone the edge node detected, and lets you look up any public IP in the registry (RDAP) to see its owning network, registering organization, and allocated address range. Only the server can observe your own IP address, so this tool requires a server round trip.
How to use IP Lookup
- 1Open the page and your connection details appear immediately.
- 2Enter any public IP address below and click Look up.
- 3Review the owning network, the registering organization, and the CIDR range.
Frequently asked questions
What is the difference between RDAP and traditional WHOIS?+
RDAP is the modern replacement for WHOIS: it returns structured JSON rather than free-form text, supports standardized differentiated access control, and is now offered by every regional registry. That makes the results far more dependable and removes the need to write a separate text parser for each RIR.
Why can't I get a precise city for an IP address?+
The registry records which organization an address range was allocated to, not where that range is physically used today. City-level accuracy depends on commercial IP geolocation databases, and even those carry a meaningful error rate, which is exactly why IP geolocation should never be a hard gate in your business logic.
Why is my location information empty during local development?+
The country and city fields come from request headers injected by the edge node, so they only exist once the app is deployed to that edge network. Seeing those fields empty on a local machine is expected behavior.
