In a computer system, the hosts file can define the mapping between IP addresses and host names. It specifies the mapped IP address and host name when the computer accesses the network and performs network settings. However, the hosts file can be opened in a text file format and view its specific content. For example, when a user enters a website in the browser, but the website needs to log in, the system will automatically find the hosts file to work. The hosts file will look for the corresponding IP address at this time, as long as the corresponding IP is found. Address, then the browser will open the corresponding page feedback to the user.

The location of the Hosts file

The server and the DNS server will perform IP address resolution for the current status in the current state, and the work that cannot be completed by the host before the completion. So where is the hosts file in the Windows system? Since it is an important system file, the location of the hosts file must be in the Windows folder of the system disk. Take Windows7 as an example. If we enter the system disk, then enter the Windows folder, and then access the folder in the order of system32-drivers-etc, then we can see the hosts file.

First, we enter the location of the hosts file, then right click on the hosts file, select the open method in the pop-up window, select to open the hosts file using Notepad, open all the contents of the notebook, and re-enter the new statement.
