Ultimate Guide: How to Check IP Address on Ubuntu

How to Check IP Address on Ubuntu

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 purposes: host or network interface identification and location addressing. IP addresses are essential for communication between devices on a network and the Internet.

There are several ways to check the IP address of your Ubuntu system. The most common method is to use the `ifconfig` command. This command will display a list of all the network interfaces on your system, along with their IP addresses.

To use the `ifconfig` command, open a terminal window and type the following command:

ifconfig

The output of the `ifconfig` command will look something like this:

eth0: flags=4163  mtu 1500        inet 192.168.1.10  netmask 255.255.255.0  broadcast 192.168.1.255        inet6 fe80::20c:29ff:fe14:c3f3  prefixlen 64  scopeid 0x20        ether 00:50:56:c0:00:08  txqueuelen 1000  (Ethernet)        RX packets 146932  bytes 191816596 (183.0 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 118614  bytes 10358185 (9.8 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

In this example, the IP address of the system is `192.168.1.10`. This is the address that other devices on the network will use to communicate with your system.

You can also use the `ip` command to check your IP address. This command is more versatile than the `ifconfig` command and provides more detailed information about your network interfaces.

To use the `ip` command, open a terminal window and type the following command:

ip addr show

The output of the `ip` command will look something like this:

1: lo:  mtu 65536 qdisc noqueue state UNKNOWN     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00    inet 127.0.0.1/8 scope host lo       valid_lft forever preferred_lft forever    inet6 ::1/128 scope host        valid_lft forever preferred_lft forever2: enp0s3:  mtu 1500 qdisc fq_codel state UP qlen 1000    link/ether 00:50:56:c0:00:08 brd ff:ff:ff:ff:ff:ff    inet 192.168.1.10/24 brd 192.168.1.255 scope global enp0s3       valid_lft forever preferred_lft forever    inet6 fe80::20c:29ff:fe14:c3f3/64 scope link        valid_lft forever preferred_lft forever

In this example, the IP address of the system is `192.168.1.10`. This is the address that other devices on the network will use to communicate with your system.
