IP Lookup (Private & Fast)
See your public IP, IPv4/IPv6 version, country/city signal and ISP/ASN. This page is privacy-first: no cookies, no logs. Below we explain how it works, what you can (and can’t) learn from an IP, and how to verify browser/DNS leaks in seconds.

Your IP & why it matters
Your IP address identifies your connection on the internet. Websites and services use it to return responses and apply security or localization rules. The geolocation attached to an IP is an estimate — usually country/region and a nearest major city — and can differ across databases or networks (mobile, VPN, CGNAT).
How it works (quick)
- Your provider assigns a public IP to your router or gateway (devices at home use private IPs).
- Sites see the public IP and look it up in one or more geolocation databases for country/city and ISP/ASN.
- Different networks (Wi-Fi vs mobile/VPN) can show different IPs and locations — that’s expected.
What you see here
| Data type | Example | Meaning | Visible to websites? |
|---|---|---|---|
| IPv4 | 203.0.113.7 | Common 32-bit address format | Yes |
| IPv6 | 2001:db8::1 | Modern 128-bit format; may co-exist with IPv4 | Yes |
| Location signal | Country → City (approx.) | Estimated from provider data | Yes |
| ISP / ASN | AS12345 (Example ISP) | Identifies provider network | Yes |
| User-Agent | Chrome on Windows | Browser string for compatibility | Yes |
Accuracy & privacy notes
- IP geolocation is approximate. It can resolve to an ISP hub or gateway rather than your exact place.
- VPN/proxy purposely shows the exit server location (by design); mobile/CGNAT can shift cities.
- No personal name or street address can be derived from an IP alone.
Verify IPv4/IPv6 and common leaks
- Open What is My IP to see your public address and version.
- Run WebRTC Leak Test to ensure the browser doesn’t expose local/public IPs unintentionally.
- Run DNS Lookup to check which resolvers your device uses (ISP or third-party).
