See your own public IP and look up any IPv4 / IPv6 - ASN, ISP, country, city.

Look up any IP
Powered by the public ipwho.is API. Your browser talks to them directly - this site never sees the address you look up.
About this tool
Shows your current public IP (both IPv4 and IPv6 when available) along with the ASN, ISP / organisation, country, region, city, latitude / longitude and timezone reported by ipwho.is. You can also paste any IPv4 or IPv6 address to look up the same information. Useful for confirming which IP your VPN is exiting from, verifying the ASN of a server you're about to whitelist, or double-checking a suspicious IP from a log file. The lookup is a plain browser fetch to a CORS-friendly public API - your machine talks directly to the provider, not to a proxy on this site.
FAQs
How does the tool know my IP?
It doesn't - the ipwho.is API sees your request and echoes back the source IP it observed. Because the fetch is made from your browser, that IP is your public IP as seen by the internet, not this site's server. VPN / proxy? You'll see the exit node.
Why don't I see an IPv6 address?
Either your ISP hasn't rolled out IPv6 to your connection, or your OS is preferring IPv4 for this destination. Try 'ipv6-only' endpoints (e.g. https://api6.ipify.org) in a terminal to confirm. The tool shows whichever address the API observed.
How accurate is the geolocation?
Country is highly accurate. City is a best-effort mapping of the IP range to a city and can be wrong by hundreds of kilometres for mobile networks, satellite ISPs and corporate VPNs. Coordinates are the city centroid, not your actual location.
What is an ASN?
Autonomous System Number - a unique ID for a network operator (e.g. AS15169 is Google, AS16509 is AWS). It's the coarsest useful identifier for who runs the IP. Useful when logs show suspicious traffic and you want to know whether it's a cloud provider, a hosting company, or a residential ISP.
Does the tool store the IPs I look up?
No. The lookup goes directly from your browser to the public API and back. This site never sees the query. ipwho.is has its own logging policy - review it if that matters to you.
