Internet protocol
Definition
Internet Protocol (IP) is a networking standard that governs how data packets are addressed, transmitted, and delivered across interconnected networks. It provides the foundation for communication on the internet, ensuring that devices can identify each other using unique IP addresses. Each data packet contains both source and destination addresses, allowing routers to forward information along the most efficient path.
For businesses, IP is fundamental to online operations, enabling websites, applications, email systems, and connected devices to function reliably across global networks. Without IP, the exchange of information that powers digital communication and commerce would not be possible.
Advanced
There are two main versions of Internet Protocol in use today. IPv4, the original standard, uses 32-bit addresses and supports about 4.3 billion unique addresses. IPv6, the successor, uses 128-bit addresses, offering virtually unlimited scalability and improved features like simplified headers and better security support.
IP operates at the network layer of the TCP/IP model and works alongside higher-level protocols like TCP, UDP, and HTTP. Advanced business networks may also rely on subnets, Network Address Translation (NAT), and IP routing policies to optimize traffic flow and security. For enterprises, the shift toward IPv6 adoption ensures long-term compatibility and support for the growing number of connected devices.
