Query IP by Using ifconfig Command

After the device is started normally and the display is connected, you can use the ifconfig command to view the current device IP.

Preparation:

The device has been connected to the network via Ethernet or Wi-Fi.

Steps:

Run the following command to view the detailed information of each port of the device, where the inet value in the eth and wlan0 interface is the device IP, as shown in the following figure.

Query IP by Using Network Manager CLI

After the device starts normally, use the nmcli device show command to check the device's current IP address.

Preparation:

The device has been connected to the network via Ethernet or Wi-Fi.

Steps:

Run the following command to view the detailed network information.

nmcli device show

Login Router to Query IP

Once the device has started normally, you can log in to the router to check the device's current IP address.

Preparation:

  • The device has been connected to the network through the router.
  • The IP and network password of the router in the network have been obtained, and the IP address is 192.168.X.X.

Steps:

  1. Open a browser, Enter the router IP of the network where the device is located in the address bar: 192.168.x.x, and press Enter to enter the router login interface.
  2. According to the interface prompts, input the network password and enter the router management interface.
  3. Find the IP address of device in the terminal device of the management interface.

Scan For Using NMAP Tool

After the device starts normally, you can use the nmap tool to scan the IP addresses on the current network to obtain device IP information. nmap supports multiple platforms including Linux, macOS, and Windows.

Preparation:

  • The device has been connected to the network through the router.
  • The IP segment and mask of the router in the network have been obtained, for example, 192.168.X.X/24, where 24 is the subnet mask.

Steps:

For example, using nmap to scan the network segments from 192.168.3.0 to 255, you can use the following steps:

  1. Open the nmap tool and scan the hosts in the 192.168.X.X/24 network segment.

WARNING

The nmap tool operates differently in different operating systems, so please follow the actual interface or command prompts.

  1. According to the scanned results, get the device IP.
