IP Address
An IP address (Internet Protocol address) is a unique numerical identifier assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two primary functions: identifying the host or network interface and providing the location of the device in the network, enabling data routing and delivery across the internet or local networks.
Developers should understand IP addresses to build and troubleshoot networked applications, configure servers, implement security measures like firewalls, and work with cloud infrastructure. This knowledge is essential for web development, network programming, cybersecurity, and DevOps roles where handling network communication, addressing, and routing is critical.
