What is an IP address?

An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to the internet. IPv4 addresses use the format 192.168.1.1, while IPv6 addresses use the longer format 2001:db8::1. Your public IP identifies you on the internet.

Can someone find my location from my IP?

An IP address reveals your approximate location (city level, typically within 25-50km accuracy) and your ISP, but not your exact street address. IP geolocation databases are approximately 80% accurate at the city level.

Why does my IP address change?

Most ISPs use dynamic IP addresses that change periodically (every 24 hours to several weeks). A new IP is assigned when your router reconnects. If you need a fixed IP, you can request a static IP from your ISP, usually for an additional fee.

What is the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses (about 4.3 billion unique addresses), while IPv6 uses 128-bit addresses (practically unlimited). IPv6 was created because the world ran out of IPv4 addresses. Both protocols currently coexist on the internet.

How do I hide my IP address?

Use a VPN (Virtual Private Network) to mask your IP with the VPN server's IP. Other options include using the Tor browser or a proxy server. A VPN is the most reliable and secure method for hiding your IP address.

It uses 128-bit addresses (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334), allowing for a vastly larger number of specialized addresses.
