In the online world, each computer will be assigned a unique IP address. This address can be used to identify the location of the computer in the network and implement data transmission and communication. Querying the IP address can help us understand the network connection status of this machine, as well as network adjustments or troubleshooting that may need to be made. This article will introduce several common methods of querying the local IP address.

The first method is to use the command line to query the IP address of the machine. In the Windows operating system, you can open the command prompt window, enter the "ipconfig" command, and then press Enter. The system will display the IP configuration information of the machine, including IP address, subnet mask, default gateway, etc. In Mac OS or Linux operating system, you can open a terminal window and enter the "ifconfig" command to query the IP address of the machine.

The second method is to query the IP address by using a third-party website. There are many online tools and websites that can provide IP address query services. One of the more common websites is ip138.com. On the home page of the website or the IP address query page, enter "local IP address query" or similar keywords to get the query results of the local IP address.

In addition to using the command line or a third-party website, you can also query the IP address of the machine through a browser extension or application. For example, there are some browser plug-ins that can display the IP address of the current web page and the IP address of the machine. Users only need to install and enable the corresponding plug-ins to query the IP address at any time. In addition, there are also some specialized IP address query applications that can be used on computers or mobile devices to provide more convenient query services.

Whether you use the command line, a third-party website, or a browser plug-in and application, querying the IP address of your machine is a relatively simple and quick operation. However, it should be noted that in some cases the IP address of the machine may be dynamically assigned and may change each time it is connected to the network. In this case, if you need to use a fixed IP address for a long time, you can contact the network operator or system administrator to apply and set it up.

To sum up, querying the IP address of the machine is one of the common operations for network adjustment and troubleshooting. Through the command line, third-party websites, browser plug-ins or applications, we can quickly obtain the IP address information of the machine to facilitate network configuration and related problem processing. Whether for personal use or business management, knowing how to query the local IP address is a very useful skill.
