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,那Win7系统电脑hosts是什么文件呢?下面小编就和大家说一下Win7系统hosts文件内容是什么。
Win7系统电脑hosts文件详解一、什么是hosts文件?
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!
二、Win7的hosts 默认文件
文件地址:C:WINDOWSsystem32driversetchosts
默认里面的内容如下:
# 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
