Click to see the surprise proxy An IP address, or Internet Protocol address, is an address used on the Internet to uniquely identify a computer or network device. It consists of 32 binary digits, usually expressed as dot-separated decimal numbers, such as 192.168.1.1. An IP address works similarly to a mailing address in that it helps route data packets to the correct destination. When you visit a website or use an application, your device sends the packet to the IP address of the destination device. IP addresses are divided into two parts: network addresses and host addresses. The network address identifies the network on which the device is located, and the host address identifies a specific device on the network. IP addresses work as follows: Your device sends packets to the IP address of the destination device. The packet arrives at the network where the target device is located. Network routers route the packet to the correct subnet based on the network address. Routers in the subnet route the packet to the target device based on the host address.[/b]
