Manage Network Interfaces From Linux Terminal With the ip Command

Newer Linux distros have the ip command rather than ifconfig for getting network interface information and for managing them from the Linux command line.

Here is a quick guide on how to use this command from the Linux terminal:

To show network information for all the interfaces, type:

ip addr show

list the network interfaces using the ip command

This will list all the network interfaces sequentially along with their status and other network details.

To get the information for a specific interface like ethernet or wireless, the command is:

ip addr show interfacename

querying for a specific network interface details using the ip command

To find a list of all the network interfaces that are currently up:

ip link ls up

showing active and enabled network interfaces using the ip command in Linux

Similarly, you can also directly enable and disable network interfaces with the ip command (just like the ifconfig up/down commands):

sudo ip link set interfacename up

sudo ip link set interfacename down

disabling a network interface using the ip command in Linux


This will enable and disable the interfaces. You can first check the interfaces using the ip addr show command and then use the link parameters.

Other than that, you can also add static IP address to a particular interface. To do that:

sudo ip addr add IP/MASK dev interfacename

So to add a static IP / to the ethernet interface eth1, the command will be:

sudo ip addr add dev eth1

For deleting the static IP:

sudo ip addr del dev eth1

The exact interface name will vary and can be found using the ip addr show command.

Also, to get the IPv4 and IPv6 details, the command is:

ip -4 a

ip -6 a

finding IPv4 and IPv6 details of the system using the ip command

Here is a quick reference table for managing network properties from the Linux terminal with the ip command:

You can also use the man ip command to know about other different parameters and functions.

man ip

using the man ip command

All done.
