What is an IP address?

An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface and providing the location of the device in the network. This is crucial for directing internet traffic efficiently, as it allows devices to locate and communicate with each other over the Internet. Each time data is sent over the Internet, it includes the destination IP address, ensuring that information reaches the correct device.

The other options do not accurately represent the concept of an IP address. For instance, a type of computer software does not pertain to how devices communicate on the Internet. Similarly, a method for encrypting data is related to security measures rather than addressing. Lastly, while a framework for web development is essential for building websites, it is not directly related to how devices are identified on the Internet. Thus, understanding the function of an IP address is fundamental to navigating the digital landscape.
