Linux IP Command Tips and Tricks

Linux IP Command Tips and Tricks

The Linux IP command is very similar to ifconfig, but it is more powerful. You can perform several network administration tasks using the IP command. Also, ifconfig is one of the deprecated commands that has not been maintained for many years even though it is still available on most Linux distributions. The IP command line utility comes with the iproute2 suite utility, and most Linux distributions will come with the iproute2 tools pre-installed.

In this post we review how we can assign Static IP Address, Static Route, Default Gateway and Assigning IP Address on demand using IP command.

Set Up and Delete an IP Address

You can set an IP address for interface eth0 using the following command:

After you have set the IP address, you can confirm whether the changes have taken effect and get the depth information of your network interfaces like IP Address and MAC Address information using the following command:

You should see the following output:


You can delete an IP address by just replacing add with del flag.

Enable and Disable Network Interface

You can enable the network interface eth0 with the following command:

To disable the network interface eth0, run the following command:

To do this, run the following command:

You should see the following output:


ARP Entries

ARP, also known as Address Resolution Protocol, is used to translate an IP address to its corresponding physical address, commonly known as MAC address. Using the IP command you can view the MAC address of the devices connected in your LAN by using the option neighbour.

You should see the following output:



The IP command is a very useful tool for every network administrator and all Linux users. It is even more useful when you are writing scripts. Let us know if this article is useful for you.
