Many Windows administrators are comfortable with displaying network information through the GUI. Confirming IP address settings is critical enough that even Windows administrators should have a basic understanding of these two commands in case they are ever signed into a Linux device. It’s a good idea for Linux administrators to get used to both the ifconfig and ip commands for displaying network configurations. Here’s an example, using the same addressing information from the ifconfig example above: To focus the command on the enp0s3 interface, simply type the following:įigure 2: Display IP address information with ip addrįinally, like ifconfig, the ip command can configure a static IP on a NIC. Like ifconfig, ip addr displays the configuration of all active interfaces. However, this command can be abbreviated down to ip addr or even just ip a. Formal training on the ip command might show the following example for displaying all IP address information: Routing and link configurations can also be manipulated.
There are many subcommands available for ip beyond the addr example displayed above. Here’s a basic example of displaying the IP configurations of all interfaces: The syntax of the ip command is different from ifconfig. Some Linux distributions have both tools installed but be aware that many have just one. It’s more robust and more complex than ifconfig. The ip command is relatively new to the Linux scene. For example, to set a default gateway of 192.168.2.1 to the system, type: # ifconfig enp0s3 192.168.2.200 netmask 255.255.255.0Īlso, note that you can use the route command to add a default gateway after setting the static IP address with ifconfig. Here’s an example of configuring the 192.168.2.200/24 address and subnet mask on enp0s3: The ifconfig command even allows administrators to set a static IP address on an interface. It’s important to note that the ifconfig command is one of several choices to display the IP address configuration on macOS. For example, you can up or down NICs (enable or disable) by using this command: Some configuration is also possible via the ifconfig command. To see the IP address for the enp0s3 interface, for example, type the following command: Depending on the system, this output can be very long, so it’s also possible to display the configuration for specific interfaces. The ifconfig command displays the network configuration for active interfaces.

During this transition, it’s critical to know how to work with both.įigure 1: Display IP address information with ifconfig While many distributions still ship with ifconfig, it is gradually being replaced with the ipcommand. The common tool for displaying IP address information in Linux has been ifconfig. Let’s discuss four ways you can display IP configurations in both Linux and Windows.
Like many tasks, displaying the IP address is more quickly done via the command line interface (CLI) than the graphical user interface (GUI). The administrator should recognize this as an Automatic Private IP Address (APIPA) configuration or link-local address that indicates the device could not successfully lease an IP address configuration from a Dynamic Host Configuration Protocol (DHCP) server.īecause the administrator can view the IP settings, they now have a course of action to make the system accessible again. The IP address displayed on the system is 169.254.10.103. As part of troubleshooting, the administrator checks the system’s IP address. Doing so allows system administrators to confirm the address is assigned and correct.Ĭonsider the following example: A system cannot be reached from across the network. One fundamental component of network troubleshooting on a server is displaying the current IP address configuration.
