Your real public IP address as seen by the internet, with ISP, location and network details.
This tool detects your real public IPv4 and IPv6 addresses simultaneously. If your network supports both protocols (dual-stack), both addresses are shown. It also shows your Internet Service Provider (ISP), Autonomous System Number (ASN), approximate city and country, timezone, and reverse DNS hostname. Your addresses are read from ipify (api4.ipify.org and api64.ipify.org), which your browser asks directly. The provider, network, location and hostname details come from ip-api.com, which VLANlab's server asks about your address; when ip-api.com has no answer, VLANlab's own data (MaxMind GeoLite2 and published network lists) fills them in.
This is very common and means your network supports IPv6 - but your laptop isn't using it. Phones (iOS and Android) aggressively request IPv6 addresses and have done so since carriers adopted it years ago. Windows laptops often don't, for a few reasons: IPv6 may be disabled in the network adapter settings, a corporate Group Policy may have turned it off, or Windows simply didn't negotiate an IPv6 lease from the router.
To check on Windows, open Command Prompt and run ipconfig /all. Under your WiFi adapter, look for an "IPv6 Address" starting with 2 or fd. If you only see a "Link-local IPv6 Address" starting with fe80, your laptop has no routable IPv6 - exactly what this tool would show. The phone and the laptop are both reporting correctly.
Why might you see different IPs in different sessions? Modern networks use the Happy Eyeballs algorithm - browsers prefer IPv6 when available. A phone on home WiFi may use IPv6 while a laptop on a corporate network falls back to IPv4 because the company gateway doesn't route IPv6. Both results are correct.
The connection type indicators reveal whether your IP address is registered to a residential broadband provider, a mobile network, a datacenter or cloud host, or a known VPN or proxy service. This is useful for verifying that a VPN is working correctly or confirming which ISP is routing your traffic.
Your public IP address identifies your connection on the internet. Websites, APIs, and online services use it for geo-targeting, rate limiting, security checks, and fraud detection. Knowing your public IP is essential for configuring firewalls, whitelisting remote access, setting up VPNs, and debugging network connectivity.
