dos command to check the ip address in the LAN

In our daily life and work, we often use computers and other devices to connect to a LAN. A LAN is composed of a group of interconnected computers and devices. Through the LAN, we can easily share files and resources. In some cases, we need to see the IP address of a device on the LAN. In Windows operating system, we can use DOS commands to achieve this purpose.

DOS command is a command line operation interface. We can enter the corresponding command in the command prompt window to perform operations. Below, I will introduce several commonly used DOS commands to view the IP address in the LAN.

The first command is "ipconfig". Enter "ipconfig" in the command prompt window and press the Enter key. The system will display the machine's IP address, subnet mask, default gateway and other information. Among them, the IPv4 address is the IP address of the local area network.

The second command is "ping". In the command prompt window, enter "ping" plus the IP address or host name of the device to be queried, and then press the Enter key. The system will send the data packet to the target device and display the IP address of the target device, as well as the IP address from your device. Network latency from computer to target device. With this command, we can determine the IP addresses of other devices in the LAN.

The third command is "arp". Enter "arp -a" in the command prompt window, and then press the Enter key. The system will display the IP address and corresponding physical address (MAC address) of the device in the LAN. Even if the device is not configured with a static IP address, you can use this command to view its dynamically assigned IP address.

The above is how to use DOS commands to check the IP address in the LAN in the Windows operating system. These commands are very useful for network administrators and ordinary users in their daily work, and can help us better understand and manage the local network. However, it is important to note that before executing these commands, we need to ensure that we have sufficient permissions to perform these operations.

To summarize, by using DOS commands, we can easily check the IP address of the device in the LAN. The ipconfig command can display the local IP address, the ping command can determine the IP address of other devices, and the arp command can display the IP address and physical address of the device in the LAN. These commands are very useful for maintaining and managing local networks, helping us better grasp and utilize network resources.
