An IP address, short for Internet Protocol address, is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.
In Linux, there are several ways to check your IP address. One common method is to use the ifconfig command. This command will display a list of all the network interfaces on your computer, along with their IP addresses. Another method is to use the hostname command. This command will display the hostname of your computer, as well as its IP address.
