How accurate is IP geolocation?

IP geolocation is generally accurate at the country level (95-99%) and city level (50-80%). Accuracy depends on the IP database used and whether the IP is from an ISP, VPN, or proxy. It should not be used as a precise physical location.

Can I look up any IP address?

Yes, you can look up any public IPv4 or IPv6 address. Private/internal IP addresses (like 192.168.x.x or 10.x.x.x) cannot be geolocated because they are not routable on the public internet.

What does this tool show?

This tool displays your IP address, country, city, region, latitude, longitude, ISP/organization, and timezone. It also shows a map preview of the approximate location using OpenStreetMap.

Does this tool store my IP address?

No. This tool sends your query directly to the ipapi.co API from your browser. We do not log, store, or transmit your IP address or any geolocation results to our servers.

VPN을 사용하면 IP 주소가 바뀌나요?

네, VPN을 사용하면 VPN 서버의 IP 주소가 표시됩니다. 실제 위치 대신 VPN 서버의 위치가 나타나므로, VPN이 제대로 작동하는지 확인하는 데도 이 도구를 사용할 수 있습니다.

IPv4 and IPv6 — what's the difference?

IPv4 addresses look like 192.0.2.1 (four groups of numbers). IPv6 addresses look like 2001:0db8::1 (longer, with colons). Both are supported by this tool. Most devices today have both types.

What Is My IP Address? — IP Geolocation Lookup

Check your public IP address instantly. This free tool auto-detects your IP and shows your country, city, ISP, and timezone. You can also look up any IP address. 내 아이피 주소를 바로 확인하세요.

What Is My IP Address?

Your IP (Internet Protocol) address is a unique numerical label assigned to your device when it connects to the internet. Every device that communicates over the internet needs an IP address, functioning much like a mailing address for digital data. When you visit a website, your device sends its IP address along with the request so the server knows where to send the response back. This tool instantly reveals your public IP address, geographic location, ISP, and timezone without any signup or software installation.

There are two types of IP addresses you should know about. Your public (or external) IP address is the one visible to websites and services on the internet. It is assigned by your Internet Service Provider and is shared among devices on your local network through NAT (Network Address Translation). Your private (or internal) IP address (like 192.168.1.x or 10.0.0.x) is only used within your local network and cannot be seen from the outside. This tool shows your public IP address, which is the one that matters for geolocation and online identity.

IP geolocation works by mapping IP address ranges to physical locations. Internet registries (ARIN, RIPE, APNIC, etc.) assign IP blocks to ISPs, which in turn assign them to regions. Geolocation databases aggregate this information along with routing data to estimate the geographic location associated with an IP. Accuracy is typically very high at the country level (95-99%) and reasonable at the city level (50-80%), though it should never be treated as a precise physical location.

How IP Geolocation Works

When you open this page, your browser sends a request to the ipapi.co API, which reads the source IP address of your request and looks it up in a geolocation database. The database maps IP ranges to geographic coordinates, ISP names, and timezone identifiers. The result is returned as JSON and displayed in the cards above, along with an interactive OpenStreetMap embed showing the approximate location.

You can also enter any public IPv4 or IPv6 address to look up its geolocation. This is useful for investigating suspicious traffic, verifying where a server is hosted, or checking whether a VPN is masking your real location. Private IP ranges (10.x.x.x, 172.16-31.x.x, 192.168.x.x) cannot be geolocated because they are not routable on the public internet.

Common Use Cases

VPN verification: After connecting to a VPN, check this tool to confirm your visible IP has changed to the VPN server location. If your real IP still shows, the VPN may be leaking.
Server location check: Enter a server IP to verify it is hosted in the geographic region you expect. This matters for latency-sensitive applications and data residency compliance.
Security investigation: When you see suspicious login attempts or traffic in your server logs, look up the source IP to identify the country and ISP of origin.
Content delivery debugging: CDNs route users to the nearest edge server based on IP geolocation. If content is loading slowly, checking the IP location can reveal routing issues.
Geo-restriction testing: Verify which region streaming services or websites see you as being in. This helps debug geo-restricted content access issues.
Network troubleshooting: Knowing your public IP is the first step in diagnosing connectivity issues. You can share it with your ISP support team when reporting problems.
Remote access setup: Setting up port forwarding, dynamic DNS, or remote desktop connections requires knowing your public IP address.

Tips and Best Practices

Your IP is not permanent: Most residential ISPs assign dynamic IP addresses that change periodically. If you need a stable IP, ask your ISP about static IP options or use a dynamic DNS service.
Geolocation is approximate: The city shown may be the location of your ISP's regional hub rather than your exact city. Never rely on IP geolocation for precise physical location tracking.
Protect your IP: Your public IP can reveal your general location and ISP. Use a VPN if you want to mask this information while browsing.
IPv6 adoption is growing: Many ISPs now assign both IPv4 and IPv6 addresses. Both formats are fully supported by this tool.
Corporate IPs may show headquarters: If you are on a corporate network, the geolocation may point to the company headquarters rather than your actual office location due to centralized internet routing.

IP Geolocation Tool vs Alternatives

Command-line tools (curl ifconfig.me): Quick for getting your IP but does not provide geolocation data. You would need to pipe the result into a separate geolocation API call.

whatismyipaddress.com: A popular dedicated IP lookup site, but often cluttered with ads and requires multiple clicks for detailed information. This tool shows everything on one page.

Browser developer tools: The Network tab shows request headers but does not directly reveal your public IP or geolocation. A dedicated tool like this one is purpose-built for the task.

MaxMind GeoIP2: A professional-grade geolocation database used by enterprises. It offers higher accuracy but requires a paid subscription and technical integration. For casual lookups, this free tool is more than sufficient.
