FAQ

Common questions about IP addresses.

What is an IP address?

An IP address is a unique identifier assigned to every device connected to the internet. It allows devices to communicate with each other.

What is the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses (e.g., 192.168.1.1) with ~4.3 billion possible addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) with virtually unlimited addresses. IPv6 is the newer standard designed to replace IPv4 as addresses run out.

Why do I only have IPv4 and not IPv6?

Many ISPs have not yet fully deployed IPv6. Your router or network equipment may also need to support IPv6. Contact your ISP to check if IPv6 is available in your area.

Can someone find my exact location from my IP?

No. An IP address only reveals approximate geographic location, typically at the city level. Only your ISP can connect your IP to your actual address.

How can I hide my IP address?

You can use a VPN (Virtual Private Network), proxy server, or the Tor network to mask your real IP address from websites.

Is this service free?

Yes! Our IP lookup is completely free for personal use. We also provide a free API for developers.
