3. ip addr

The “ip addr” command is a powerful tool for managing and configuring network interfaces in Linux. It provides a wealth of information about network interfaces, including their IP addresses, MAC addresses, and other settings. In the context of “how to check IP of Linux machine”, the “ip addr” command plays a crucial role.

• Detailed network interface information:

  The “ip addr” command provides detailed information about each network interface, including its name, MAC address, IP addresses, and other settings. This information is essential for understanding how the machine is connected to the network and communicating with other devices.

• IP address management:

  The “ip addr” command can be used to manage IP addresses assigned to network interfaces. This includes adding, removing, and modifying IP addresses. This capability is essential for configuring static IP addresses or setting up complex network configurations.

• Network troubleshooting:

  The “ip addr” command can be used to troubleshoot network issues by providing detailed information about network interfaces and their IP addresses. This information can help identify problems such as IP address conflicts, incorrect network configurations, and faulty hardware.

• Advanced network configuration:

  The “ip addr” command provides advanced options for configuring network interfaces. These options include setting up VLANs, bonding multiple network interfaces, and configuring IPv6 addresses. This capability is essential for advanced network administration and customization.

In summary, the “ip addr” command is a versatile and essential tool for managing network interfaces and checking the IP address of a Linux machine. Its ability to provide detailed information, manage IP addresses, troubleshoot network issues, and perform advanced network configuration makes it an indispensable tool for network administrators and system engineers.
