An IP address is a unique numerical label assigned to each device connected to a computer network, like the internet, for communication. It functions like a digital street address, allowing devices to send and receive data to the correct destination. This is essential for everything from browsing websites to sending emails, as IP addresses are used to route information across networks.

Key aspects of an IP address

Unique identification: Each device on a network, such as a computer, smartphone, or smart home device, has its own unique IP address.

Enables communication: It is the foundational element that allows devices to communicate with each other by providing a unique address for them.

Functionality: Without an IP address, a device cannot connect to the internet or other networks to send or receive data.

Similar to a phone number: An IP address is analogous to a phone number; it's a unique number that allows your device to be found and connected with others, just as a phone number connects calls.
