What Is My IP & Client Connection Detector
Detect your public IPv4 or IPv6 address, reverse DNS hostname, ISP network provider, and geographic gateway location instantly.
Live Client IP Detection & Connection Diagnostics
Your public IP address is the unique numerical identifier assigned to your Internet connection by your ISP, visible to all external servers across the global web.
Verifying your live public IP confirms whether your connection is routed through a CGNAT pool, an active VPN tunnel, or a dedicated public static IP.

What Is My IP & Client Connection Detector Engineering FAQs
What is the difference between a Public IP and a Private IP address?
Public IPs are globally routable across the internet. Private IPs (e.g., 192.168.x.x, 10.x.x.x) operate inside local LANs behind NAT routers.
How do I check if my ISP has placed me behind CGNAT?
Compare the WAN IP reported inside your home router's status page with what this tool detects. If your router WAN IP is in the 100.64.0.0/10 range, you are behind CGNAT.
Can my public IP address reveal my physical street address?
No. Public IP geolocation identifies your ISP POP city or regional routing hub, not your personal street address.
