IP (Internet Protocol) is a network layer protocol used for addressing and routing data packets in networks such as the Internet. It defines the rules for data transmission between devices.
Main characteristics of IP:
- Connectionless: IP does not establish a persistent connection between sender and receiver. Each data packet is sent independently.
- Unreliable: IP does not guarantee delivery, order, or error checking. These functions are typically handled by higher-level protocols like TCP.
- Addressing: Each device in the network has a unique IP address used for identification and location.
There are two main versions of IP:
- IPv4: Uses 32-bit addresses written as four decimal numbers separated by dots (e.g., 192.168.1.1). The number of available addresses is limited.
- IPv6: Uses 128-bit addresses, providing a vastly larger address space. Addresses are written in hexadecimal separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
An IP packet contains data and a header with source and destination IP addresses, protocol version info, service type, and other parameters. Routers use IP addresses in headers to determine the optimal path for data to reach its destination.
