Supports IPv4 (e.g. 8.8.8.8) and IPv6 (e.g. 2001:4860:4860::8888). Leave empty to look up your public IP automatically.
An IP address (Internet Protocol Address) is a unique identifier assigned to a network device for sending and receiving data. Two versions are mainly in use today: IPv4 (32-bit, e.g. 192.168.1.1) and IPv6 (128-bit, e.g. 2001:db8::1).
IP geolocation does not come from GPS. It is estimated from public IP allocation records maintained by the regional internet registries (ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC), combined with the registered address of the ISP. Country-level accuracy is high; city-level accuracy has a margin of error within tens of kilometers.
• Multi-source fallback: automatically switches from ipapi.co to ipwho.is when the primary source is unavailable
• Dual-stack support: full IPv4 and IPv6 address lookup
• One-click copy: copy any single field or all info at once
• Pure frontend: the browser calls public APIs directly, with no proprietary server in between
The tool is straightforward: it supports automatic detection of your own public IP as well as lookup for any IP address, with results displayed in real time and one-click copying. Here is the detailed workflow:
Step 1: Enter an IP address. Type the IPv4 or IPv6 address you want to look up into the input field. Standard formats are supported, such as 8.8.8.8 (IPv4) and 2001:4860:4860::8888 (IPv6). To check your own public IP, leave the field empty or click the "📍 My IP" button.
Step 2: Run the lookup. Click the "🔍 Lookup" button or press Enter. The tool calls public IP geolocation APIs directly from the browser. To maximize availability, it has a built-in multi-source fallback: it first tries ipapi.co, and if that service is unavailable or times out, it automatically switches to ipwho.is. While querying, the status badge shows "Looking up..."—please wait briefly.
Step 3: Review the results. On success, the result area shows IP version (IPv4/IPv6), country, region, city, postal code, latitude/longitude, timezone, UTC offset, ASN, and ISP/organization. Each field has a "Copy" button on the right to copy that field individually. If coordinates are present, a Google Maps link is generated automatically so you can view the approximate location.
Step 4: Copy all information. Click the "📋 Copy All" button below the results to copy the complete lookup output as structured text to the clipboard, ready to paste into documents or share with others. Click "🔄 Refresh My IP" to re-query your current public IP.
Network troubleshooting: When experiencing access issues, high latency, or blocks, looking up the target server’s IP and its geographic location can help determine whether the problem is regional or ISP-specific. Combined with traceroute, this can quickly isolate network bottlenecks.
VPN and proxy verification: After connecting to a VPN or proxy, you can quickly verify whether your exit IP has changed to the expected country or region by checking the country, city, and ISP in the results. This also helps confirm the proxy is working and whether there is a DNS leak.
Security audits and log analysis: When processing server access logs or security alerts, administrators often need to determine the origin of traffic from IP addresses. Batch lookups of suspicious IPs for geolocation, ASN, and ISP information help identify malicious sources, inform geo-blocking decisions, and generate geographic distribution data for security reports.
IP address allocation: Global IP addresses are managed by IANA and distributed to five Regional Internet Registries (RIRs): ARIN (North America), RIPE NCC (Europe), APNIC (Asia-Pacific), LACNIC (Latin America), and AFRINIC (Africa). RIRs further delegate address blocks to National Internet Registries (NIRs) and Local Internet Registries (LIRs, i.e., ISPs). The data returned by this tool comes from these public allocation records.
ASN (Autonomous System Number) system: An ASN uniquely identifies an independent network administrative domain in BGP routing. Each ISP, large enterprise, or datacenter typically holds one or more ASNs. Looking up the ASN of an IP address reveals the network operator and its peering relationships, which is valuable for network engineers analyzing routing paths and ISP service quality.
Geolocation accuracy and privacy: Country-level IP geolocation is usually highly accurate (>95%), but city-level accuracy can vary by tens of kilometers because the registered address of the ISP may differ from the user’s physical location. IP geolocation points to the ISP’s network exit or datacenter, not a personal address. For privacy, this tool does not log any query history; all requests are made directly by the browser without passing through an intermediate server.
No. Looking up any public IP submits only the IP itself, with no cookies or personal identity information, and the request is sent directly from your browser without passing through a proprietary server.
Yes. This tool fully supports both IPv4 and IPv6 lookups, automatically detecting the address type and showing the corresponding geolocation, ISP and ASN information.
Country-level accuracy is usually high, while city-level has some margin of error. The located point is the ISP datacenter or exit, not the user's real physical address.
Yes. Free IP APIs each have their own rate quotas (e.g. ipapi.co free tier allows about 1000 requests/day). This tool has a built-in multi-source fallback to maximize availability.
