Win7系統hosts文件內容如何使用

   一、什麼是hosts文件?

  hosts是一個沒有擴展名的系統文件,其基本作用就是將一些常用的網址域名與其對應的IP地址建立一個關聯“數據庫”,

  當用戶在浏覽器中輸入一個需要登錄的網址時,系統會首先自動從Hosts文件中尋找對應的IP地址,一旦找到,系統會立即打開對應網頁,如果沒有找到,則系統再會將網址提交DNS域名解析服務器進行IP地址的解析,如果發現是被屏蔽的IP或域名,就會禁止打開此網頁!

  # 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
