What is my IP address?

Your public IP address is the unique number that identifies your network on the internet. Every website you visit can see this number. It usually maps to your approximate city and your internet service provider, but not your specific street address.

Partially. Your IP can reveal your approximate city and your ISP, and over time it can be used as one signal among many for tracking. But it can't directly reveal your name, home address, or accounts. To untie your activity from your IP, use a VPN, Tor, or a privacy browser.

IPv4 is the older format with about 4.3 billion addresses (e.g. 203.0.113.5). IPv6 is the newer format with effectively unlimited supply (e.g. 2001:db8::1). Most users have both today and rarely notice the difference. Modern devices prefer IPv6 when both work.

The most common way is a VPN — it routes your traffic through a server you choose, so websites see the VPN's IP instead of yours. Tor offers stronger anonymity at the cost of speed. Switching from Wi-Fi to cellular data also gives you a different IP without any setup.

IP geolocation is approximate, not GPS-accurate. Mobile carrier IPs often resolve to central data centers far from where you actually are. CGNAT pools, VPNs, and cloud egress also produce results that don't match your physical location. Country is usually right; city is often roughly right; street is never available.

A public IP is what websites see — assigned by your ISP to your router. A private IP is used inside your home network — assigned by your router to your devices (typically 192.168.x.x or 10.x.x.x). Your router translates between the two using NAT.

Mostly yes, in the same sense it's "safe" to share your phone number. Sharing an IP doesn't let someone hack you any more than sharing your phone number lets someone steal your identity. Most home networks are firewalled by default, and exploits require specific vulnerabilities, not just an IP.

The fastest way is to load this page — your public IP appears at the top. For your private IP (the one inside your home network), check your operating system's network settings: ipconfig on Windows, ifconfig on macOS or Linux, Wi-Fi settings on iOS and Android.
