IP Check

Check your current outbound IP, location, ASN/ISP, and test connectivity to popular sites.

Current outbound info

Data from public IP geolocation APIs. Results may vary due to database update delays.

Connectivity test

Test if a target site is reachable from your browser.

About IP Check

Your IP address is your device's unique identifier on the internet. Knowing your public IP, geographic location, ISP (Internet Service Provider), and ASN (Autonomous System Number) is useful for troubleshooting network issues, verifying VPN connections, checking if your traffic is correctly routed, or understanding which regional App Store you are connected to.

This tool queries multiple public IP geolocation APIs — including ipwho.is, ipapi.co, and ipinfo.io — and displays the combined result. It shows your IP, country with flag emoji, city, timezone, ASN, ISP name, organization, and approximate coordinates. The result is fetched client-side, so it reflects your browser's actual outbound address.

The Connectivity Test section lets you quickly verify whether common sites — Google, GitHub, YouTube, ChatGPT, and the App Store — are reachable from your browser. Choose a target URL or type your own. The test measures response time in milliseconds and indicates reachability. This is especially useful when debugging proxy or DNS configurations.

Tip: use the Refresh button to re-query if your network environment changes (e.g., switching Wi-Fi or toggling a VPN). IP geolocation databases are not real-time — results may show cached or approximate locations. Compare results across the three API sources for the most accurate ASN data.

How It Works

The IP Check tool queries public geolocation databases and WHOIS registries to resolve IP address information. When you enter an IPv4 or IPv6 address, the tool performs a reverse lookup against multiple data sources — regional internet registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC), ISP allocation databases, and commercial geolocation providers.

The returned data includes approximate geographic location (country, region, city), Internet Service Provider name, Autonomous System Number (ASN), and organization details. ASN is particularly useful for understanding which network operator controls the IP block — this matters for evaluating whether an IP belongs to a cloud provider, a residential ISP, or a corporate network.

IP geolocation is inherently approximate. Commercial databases typically achieve country-level accuracy above 95%, city-level accuracy around 60-80%, and street-level accuracy is unreliable. The tool displays ASN organization details sourced from WHOIS, which is more authoritative than geolocation for identifying IP ownership.

Pro Tips

  • VPN verification: if your VPN claims a specific country, use this tool to confirm your real outbound IP matches the expected location.
  • ASN matters for App Store: your App Store region is partly determined by your IP’s country. Check ASN/ISP if the store shows the wrong region.
  • Test before troubleshooting: the connectivity test helps isolate whether a site is globally down or just unreachable from your network.
  • Compare API results: different geolocation databases update at different intervals. If results conflict, the majority answer is usually correct.
  • Mobile vs Wi-Fi: IP info differs between cellular and Wi-Fi. Check both to understand how your connections appear to external services.

Common Issues

  • Location seems wrong: IP geolocation is approximate. Databases may show the ISP’s registered address rather than the user’s physical location. This is normal and expected.
  • IPv6 shows less detail: IPv6 geolocation coverage is improving but still less complete than IPv4. Some databases only return country-level data for IPv6 addresses.
  • VPN detection: some IPs routing through VPNs or proxies will show the VPN server location, not the real user location. This is by design — IP lookup shows where the connection terminates, not where it originates.
  • Private IPs return no data: addresses like 192.168.x.x, 10.x.x.x, and 172.16-31.x.x are private and not routable on the public internet. These will return no geolocation data.

How to read IP check results

The IP page helps you understand current network exit, geolocation, ISP/ASN, and basic connectivity. It cannot precisely prove your real physical location or replace professional network diagnostics.

Geolocation is database estimation

Different IP databases can report different cities or operators. Mobile networks, data centers, and proxy exits are especially likely to show approximate or inconsistent locations.

Connectivity tests have limits

Reachability can be affected by DNS, browser behavior, CORS rules, and local network conditions. A single failure does not necessarily mean a service is down.

Privacy reminder

The page displays information your browser can obtain. When using public Wi‑Fi, proxies, or enterprise networks, avoid logging into sensitive accounts in untrusted environments.

How it works

When you open this page, the tool automatically detects your current public IP address via browser network APIs and server-side headers. It then queries multiple IP geolocation databases to resolve your approximate country, region, city, ISP, and ASN. At the same time, it performs lightweight connectivity tests against a curated list of commonly accessed services (DNS resolvers, CDN endpoints, regional mirrors) to help you gauge whether your network path is working normally. All processing happens server-side—your IP is not stored or shared.

Troubleshooting common issues

Location shows wrong city: IP geolocation databases often reflect your ISP's point of presence rather than your physical address. Mobile carriers and VPNs amplify this. If the location is critical, cross-check with a different IP lookup service. || Connectivity test fails: DNS blocking, firewall rules, and CORS policies can cause individual tests to fail even though the service is reachable directly. Test the same URL in a new browser tab. If multiple tests fail, check your local network, proxy settings, or try switching DNS servers. || No data at all: If the page loads blank, check that JavaScript is enabled and that no browser extension is blocking the fetch requests. Ad blockers and privacy extensions can sometimes interfere with the geolocation API calls.
