IP Address Checker
Check your public IP address, location, ISP, and network details.
Why Use IP Address Checker?
If you just enabled a VPN, switched networks, or suspect a captive portal is NAT'ing you somewhere weird, the first thing to check is what public IP the world actually sees. This tool gives you that address plus ISP, country, and ASN at a glance. It's also the fastest way to verify that your VPN is actually terminating where you configured it — a common silent failure is a VPN tunnel that drops back to the ISP IP without reconnecting.
How to Use IP Address Checker
- Your IP address and network information are loaded automatically when you open this tool.
- View your public IP address, country, city, ISP, timezone, coordinates, and other network details.
- Click the copy button next to your IP address to copy it to your clipboard.
- Use the 'Refresh' button to fetch updated information if your network has changed.
Worked Examples
Before and after enabling a VPN
VPN off
IPv4: 203.0.113.42 · ISP: Comcast · Location: Seattle, WA, US
Then enable VPN connected to a London exit…
After enabling VPN
VPN on (London exit)
IPv4: 198.51.100.12 · ISP: Mullvad VPN · Location: London, GB
If location still shows Seattle, the VPN tunnel isn't actually active — troubleshoot the client.
Checking an IPv6 rollout
Home fiber with dual-stack
IPv4: 203.0.113.42 · IPv6: 2001:db8:85a3::8a2e:370:7334 · ISP: Example Fiber Co · ASN: AS64501
Seeing both IPv4 and IPv6 confirms dual-stack is working.
About IP Address Checker
The IP Address Checker instantly reveals your public IP address along with detailed geolocation and network information. When you connect to the internet, your ISP assigns you a public IP address that websites and services use to communicate with your device. This tool looks up that address and provides associated metadata including your approximate geographic location (country, city, region), your Internet Service Provider (ISP), timezone, geographic coordinates, and autonomous system (AS) number. This information is useful for troubleshooting network issues, verifying VPN connections, checking your geographic IP location, or understanding how websites see your connection. The tool fetches data from a geolocation API and displays it in an easy-to-read format with one-click copy functionality.
Troubleshooting & Common Issues
Reported city is wrong or a state/country away
IP geolocation uses ISP-allocation data, not GPS. Your ISP routes traffic through a regional hub, and databases may report the hub's city rather than yours. If you need accurate location for a legal or compliance reason, don't rely on IP geolocation alone — use GPS via browser permission or an address verification service.
The tool keeps showing my old IP after I changed networks
Some browsers cache DNS and network responses aggressively. Hit the Refresh button in the tool, or open the page in a private window to force a fresh lookup. If the result still looks stale, restart the browser process — background service workers occasionally hold onto old network context.
IPv6 field is blank
Not every ISP or network has IPv6 enabled. Many home routers also disable IPv6 by default. If you need IPv6, check your router's LAN settings or contact your ISP. A missing IPv6 field doesn't break anything — the internet still works over IPv4.
"Lookup failed" or partial data
Ad blockers and privacy extensions sometimes block the geolocation API. Try disabling the extension for this page, or test in a different browser. If the failure is intermittent, it's usually a transient API rate-limit — wait a minute and retry.
Frequently Asked Questions
Is my IP address the same as my location?
Your IP address reveals your approximate location (usually city-level accuracy), not your exact address. IP geolocation databases map IP ranges to geographic regions based on ISP allocation data. The accuracy varies — it's typically within 10-50 miles of your actual location.
Why does my IP location show a different city?
IP geolocation is based on where your ISP routes traffic, not your physical location. Your ISP may route your connection through a hub in a nearby city. VPN and proxy users will see the location of their VPN/proxy server instead.
What can someone do with my IP address?
An IP address alone provides limited information — approximate location and ISP. It cannot reveal your identity, exact address, or personal data. However, it's still good practice to use a VPN on public networks for added privacy.
How do I change my IP address?
You can change your visible IP by using a VPN service, connecting to a different network, or restarting your router (which may assign a new dynamic IP). Most residential ISPs use dynamic IP addresses that change periodically on their own.
What's the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses (e.g., 203.0.113.42), giving ~4.3 billion possible addresses — not enough for the modern internet. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) with a practically unlimited pool. Most modern ISPs run both in parallel (dual-stack).
What is an ASN and why does it matter?
An Autonomous System Number (ASN) identifies a network operator on the internet — your ISP, a cloud provider like AWS, or a corporate network. ASNs are useful for deep troubleshooting (e.g., tracing BGP routing issues) and for identifying whether traffic is coming from a residential, hosting, or data-center network.
Can websites see my IP address even if I'm in incognito mode?
Yes. Incognito/private mode only prevents your browser from saving local history and cookies — your IP address is still visible to every server you connect to, because routing the request requires it. Use a VPN, Tor, or a proxy if you need to hide your IP from the destination site.
