This article mainly introduces the role of the hosts file, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

The hosts file is a computer file used to store the information of each node in the computer network; its function is to establish an associated "database" between some commonly used URL 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 find the corresponding IP address from the Hosts file.

What is the hosts file:

1. Hosts file is a computer file used to store the information of each node in the computer network.

2. This file is responsible for mapping the host name to the corresponding IP address.

3. Hosts files are usually used to supplement or replace the functions of DNS in the network.

4. Unlike DNS, the user of the computer can directly control the hosts file.

5. Hosts file location: C:\ Windows\ System32\ drivers\ etc

The purpose of the hosts file:

1. Hosts files can also be used in other situations, such as redirecting known advertising servers to an ad-free machine (usually the local IP address: 127.0.0.1) to filter ads.

At the same time, bandwidth can be reduced by not downloading online ads.

Using hosts files also reduces access to the DNS server to speed up access and reduce bandwidth consumption.

2. Another important use of hosts files is to block requests from malicious websites so as to prevent visiting fraudulent websites or infecting some viruses or malware.

But at the same time, this file may also be used by viruses or malware to prevent users from updating antivirus software or visiting specific websites.

3. You can also modify the hosts file to force the site to be assigned to the correct IP, thus accessing sites that cannot be accessed for some reason.

In addition, hosts files are often used in some software, which is based on the principle that the software automatically connects to the official server to verify information.

The function of hosts is to establish an associated "database" between some commonly used URL domain names and their corresponding IP addresses. When users enter a URL that needs to be logged in in the browser, the system will first automatically find the corresponding IP address from the Hosts file, which is helpful for everyone to operate the computer.
