Its function is to establish an associated "database" between some commonly used website domain names and their corresponding IP addresses. , when the user enters a URL that needs to be logged in in the browser, the system will first automatically search for the corresponding IP address from the Hosts file. Once found, the system will immediately open the corresponding web page. If not found, the system will submit the URL again. The DNS domain name resolution server performs IP address resolution.
