没有就没有吧，通常用不到。# 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这是win7的，如果灶模你学过编程就能看出来，前面加#号的是“注释语句”说明语句，不是要执行的语句。这玩意巧辩姿的语法规则是一个ip地址，后面加一个“域名”，比方谷歌地球不能“正常”登录，谷歌地球里面的图片服务器不能登录，就给计算机一个ip地址“指向”特定的服务器。有些“手机”越狱“翻墙的意思。但是能不能翻过去就是另孝绝外一回事了。正常的使用”国内“网络，用不到这个东西。
