Q: What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses (e.g., 192.168.1.1) supporting ~4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) supporting virtually unlimited addresses.
Q: What are IP classes?
IPv4 addresses are divided into classes A (1-126), B (128-191), C (192-223), D (224-239, multicast), and E (240-255, reserved). Class determines the default network/host split.
Q: What is a private IP address?
Private IPs are reserved for internal networks: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. They are not routable on the public internet.
Q: Is my data secure?
IP detection uses the ipify.org API. All IP analysis and validation is performed entirely in your browser. No data is stored on any server.
Q: Why does my IP look different from my local IP?
This tool shows your public IP assigned by your ISP, which differs from your local/private IP used within your network (e.g., 192.168.x.x).
