What is an IP address?

An IP address serves as a unique identifier for devices on a network, particularly on the internet. It functions much like a mailing address for devices, enabling them to send and receive data across the network. Each device that connects to the internet is assigned an IP address, ensuring that data can be accurately routed to the correct destination. The distinctiveness of the IP address allows for proper communication between devices, as it prevents data from being sent to the wrong recipient.

While other options present different concepts related to networking and security, they do not accurately encapsulate the definition of an IP address. Understanding the role of an IP address is fundamental for grasping how networks operate and how devices communicate with each other in the digital realm.
