![]() In the previous examples, we saw that the ip command shows meaningful information. In the above output, we can see that the interface name, ethernet address, and state are highlighted in different colors. Let’s use the -color option of the command to display the output in different colors: $ ip -color addr show eth2 This option highlights important details in different colors. In such cases, we can enable the colored output. However, sometimes we need to take a look at the limited information. The ip command shows detailed information about the network objects. How to Display IP Address in Colored Output To display the IP address of the individual network interface, just need to provide the network interface name as an argument to the command. Here, we can see that, now output shows the IP addresses of all network interfaces along with other details. To overcome this limitation, we can use the addr object with the ip command. However, it doesn’t show the IP address associated with the network interface. So far, we used the link object shows detailed information about the network interfaces. $ ip link show eth2Ĭheck the IP Address of the Network Interface To get the depth information of your individual network interface like IP Address, and MAC Address information, use the following command as shown below. How to Check an IP Address of a Specific Network Interface The above output shows the details of all network interfaces, such as interface name, flags, status, link address, broadcast address, etc. Now, let’s display all network interfaces using the following command: $ ip link show We can use the show command with it to display all network interfaces. In ip command, the link object represents the network interface. Note: Unfortunately all these settings will be lost after a system restart. Temporary Configure Static IP Address in Linuxįor temporary network configurations, you can use the ip command to assign an IP address to a specific interface ( eth2) on the fly. Next, restart network services after entering all the details using the following command. To configure the permanent static IP address, you need to modify your network interface configuration file /etc/network/interfaces to make permanent changes as shown below for Debian-based distributions. # vi /etc/sysconfig/network-scripts/ifcfg-eth0 Ĭonfigure Static IP in RHEL Systems Set Static IP Address in Debian Systems For example, assigning IP Address to eth0 interface as follows on RHEL-based distributions. Open and edit the network configuration files for ( eth0 or eth1) using your favorite text editor. You must be a superuser with a su (switch user) command from the terminal or command prompt. To permanently configure a static IP address in Linux, you need to update or edit the network configuration file to assign a static IP address to a system. Permanently Configure Static IP Address in Linux Note: Please take a configuration file backup before doing any changes. How to Flush IP Addresses of Network Interface How to Remove an IP Address From the Network Interface Temporary Configure Static IP Address in Linux Set Static IP Address in Debian Systems.The ip command is much similar to the old ifconfig command, but it is greatly more powerful with more functions and capabilities added to it. It is a part of the iproute2 package and offers several network administration tasks such as bringing up or down network interfaces, assigning and removing IP addresses and routes, managing ARP cache, and much more. The ip command is a new networking command-line utility that is used to assign an IP address to a network interface or configure/update useful network variables on a Linux system. However, most Linux users prefer to use the ip command due to its simplicity and rich functionality. There are a variety of graphical and command-line tools available in the market. System administrators often need to perform networking tasks on Linux servers. By the end of this guide, users will be able to perform networking tasks efficiently in Linux from the command line interface. Brief: In this guide, we will discuss some practical examples of the ip command.
