Linux ip command

In Linux, the “ip” command is used to manage and manipulate network interfaces and routing tables. It provides a comprehensive set of functionalities for network configuration, troubleshooting, and monitoring. Here’s how to use the “ip” command:

1. Open a Terminal:
   Launch a terminal emulator on your Linux system.
2. Type the “ip” command:
   The basic syntax of the “ip” command is as follows:

   ip [options] [object] [command]

• The “[object]” represents the network object you want to manipulate, such as “address,” “link,” “route,” etc.
• The “[command]” represents the specific operation or action you want to perform on the object. For example, to display information about network interfaces, you can use the following command:

   ip addr show

The “ip addr show” command will display the details of all network interfaces, including their IP addresses, MAC addresses, and associated settings.

3. Displaying Object Information:
   You can use various options and objects with the “ip” command to perform specific tasks. Some commonly used objects include:

• “address”: Manipulate IP addresses and related settings.
• “link”: Manage network interfaces (e.g., Ethernet, Wi-Fi).
• “route”: Manage routing tables and routes.
• “neigh”: Manipulate ARP cache entries.
• “link show”: Display information about network interfaces.
• “route show”: Display routing table information.
• “addr show”: Display IP addresses assigned to network interfaces. For example, to display the routing table, you can use the following command:

   ip route show

The “ip route show” command will show the current routing table, including destination networks, gateway addresses, and interface associations.

4. Modifying Object Properties:
   The “ip” command allows you to modify object properties. For example, to change the IP address of a network interface, you can use the following command:

   ip addr change <new IP>/<subnet mask> dev <interface>

Replace “” with the desired IP address, “” with the subnet mask in CIDR notation, and “” with the name of the network interface.

5. Adding and Deleting Objects:
   You can add or delete objects using the “ip” command as well. For example, to add a new IP address to a network interface, you can use the following command:

   ip addr add <IP>/<subnet mask> dev <interface>

To delete an IP address from a network interface, you can use the following command:

   ip addr del <IP>/<subnet mask> dev <interface>

Replace “” with the IP address to add or delete, “” with the subnet mask in CIDR notation, and “” with the name of the network interface.

6. Further Exploration:
   The “ip” command provides many more options and functionalities for advanced network configuration and troubleshooting. You can refer to the command’s manual page for detailed information by typing:

   man ip

The manual page will provide you with a comprehensive guide to using the “ip” command, including all available options, objects, and commands.

The “ip” command is a powerful tool for managing network interfaces, routing tables, and related network settings in Linux. By understanding its usage and options, you can configure and troubleshoot your network connections effectively.
