An IP address serves as a unique identifier for devices connected to a TCP/IP network, facilitating smooth communication over the Internet. Every device that connects to the Internet is assigned its own Internet Protocol (IP) address, which allows computers from different networks to locate and communicate with each other effectively. This is essential for all Internet-based activities, yet many users may not know their own IP address.
Proper management of IP addresses is vital for maintaining network efficiency and organization. IP addresses can be divided into two main categories: external and local. Both serve the same purpose of identifying devices, but they differ primarily in scope. External IP addresses are used for communication over the Internet, while local IP addresses function within private networks. Understanding these distinctions is crucial for effective network management and ensures seamless connectivity among devices.
