hosts原文件是什么？

Hosts是一个没有扩展名的系统文件，可以用记事本等工具打开，其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”，还是比较重要的一个文件。

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，可以简化上网流程。

Hosts文件位置

windows 用户HOSTS文件是在“c:\windows\system32\drivers\etc，这个文件一定是在系统盘，如果你的系统在D盘请自行修改前面的盘符。

下面代码粘贴到记事本保存为hosts就行不要有后缀名

# Copyright (c) 1993-2009 Microsoft Corp.

#

# 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.

#127.0.0.1 localhost

#::1 localhost
