hosts是什么文件_window7如何修改hosts

hosts文件内容是什么?hosts是一个没有扩展名的系统文件，其基本作用便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”。有些用户不小心删除了hosts文件，就需要重新建了一个hosts文件。今天主编为大家共享一下hosts文件默认的内容。

　　win7的hosts 默认文件

　　文件地址：C：winsystem32driversetchosts

　　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 win.

　　#

　　# This file contains the mappings of ip addresses to host names. Each

　　# entry should be kept on an inpidual 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 inpidual

　　# 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
