What Is My IP Address - Public IP Check

What Is My IP Address?

This tool instantly detects your public IPv4 and IPv6 addresses as seen by external servers. It also identifies your ISP, ASN (Autonomous System Number), approximate geolocation, and whether you are behind a proxy or VPN. Understanding your public IP is the first step in network reconnaissance and privacy assessment.

How It Works

When you visit this page, your browser connects to our edge server. The server reads your IP from the connection metadata — no client-side detection needed. We then perform ASN lookups and proxy heuristics to enrich the result. All processing happens at the Cloudflare Workers edge, so results are instant.

FAQ

What is the difference between public and private IP?

A private IP (e.g. 192.168.x.x) is used within your local network. A public IP is assigned by your ISP and is visible to every server you connect to. This tool shows your public IP — the address websites and services actually see.

Why does my IP address change?

Most ISPs assign dynamic IPs that change periodically or when your router restarts. If you need a stable IP for hosting or security rules, request a static IP from your ISP or use a VPN with a fixed exit node.

Can this tool detect VPN or proxy usage?

Yes. We check known datacenter and proxy ASN ranges, hosting provider IP blocks, and common VPN exit nodes. The result shows whether your connection appears to originate from a residential, hosting, or proxy network.
