An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network. It serves two main functions: identifying the host or network interface, and providing the location of the host in the network.
Your IP address is assigned by your Internet Service Provider (ISP). When you visit a website, your IP address is visible to the web server, which can use it to determine your approximate geographic location. This is how websites show you localized content or restrict access based on region.
The Internet originally used IPv4, which provides about 4.3 billion unique addresses. With the explosive growth of Internet-connected devices, IPv4 addresses were exhausted. IPv6 was developed to provide 340 undecillion addresses (340 followed by 36 zeros), ensuring the Internet can continue to grow.
An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to the Internet. It allows devices to communicate with each other. IPv4 addresses look like 192.168.1.1, while IPv6 addresses are longer like 2001:0db8:85a3::8a2e:0370:7334.
Most home internet connections have dynamic IP addresses that change periodically. Your ISP assigns a new IP each time your router reconnects. Static IPs are available for an additional cost. Mobile connections typically change IP addresses frequently.
An IP address reveals only your approximate location at the city or region level, not your exact street address. Your ISP knows your identity, but websites can only see your general geographic area based on IP geolocation databases.
You can hide your IP address using a VPN (Virtual Private Network), which encrypts your traffic and routes it through a server in a different location. The Tor browser provides even stronger anonymity. A proxy server is another option but offers less security.
IPv4 uses 32-bit addresses (about 4.3 billion unique addresses) and looks like 192.168.1.1. IPv6 uses 128-bit addresses (340 undecillion addresses) and looks like 2001:0db8:85a3::8a2e:0370:7334. IPv6 was created because IPv4 addresses ran out.
