hosts文件修复方法：

hosts文件的重要性想必很多人都不知道，下面小编先为大家介绍hosts文件的作用

hosts是一个没有扩展名的系统文件，其基本作用就是将一些常用的网址域名与其对应的IP地址建立一个关联数据库，

　　当用户在浏览器中输入一个需要登录的网址时，系统会首先自动从Hosts文件中寻找对应的IP地址，一旦找到，系统会立即打开对应网页，如果没有找到，则系统再会将网址提交DNS域名解析服务器进行IP地址的解析，如果发现是被屏蔽的IP或域名，就会禁止打开此网页！

那么如果hosts文件出错了该怎么办呢？下面就就随小编一起来学习一下hosts文件修复方法吧。

方法一：

1、在c盘C:WindowsSystem32driversetc文件夹中找到hosts文件

2、右键使用记事本打开

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
