一.HOSTS工作原理:

我 们喜欢某个网站,通常会记下它的域名以便下次访问,因为域名比IP更容易被记住。hosts文件里存放的是一些常用的网站主机的域名和其对应的IP地址, 它是用来提高解析效率的。当我们通过浏览器或者ping某个域名时,系统会首先检查本地的hosts文件是否已经有相应的域名与IP地址的映射关系,如果 有就会直接采用,如果没有,再向已知的DNS服务器(Domain Name Server)请求进行域名解析完成域名与IP的转换工作。也就是说最终网络上是通过IP来辨认你要访问的目标网站的。


通 常,我们访问不了Google、Twitter、Facebook之类的是因为有我们强大的Great FireWall(GFW)进行了DNS劫持和DNS污染。GFW会对DNS的解析过程进行干扰,这会使对某些被干扰的域名返回一个错误的IP地址给你的 主机,使你无法正确连接到你要的服务器,或者请求后返回不是原有的数据。当我们直接将 IP放入Hosts文件后,就可以跳过DNS的解析这一步,直接就行IP访问,翻过GFW。


但是,GFW也会对一些“重点”网站进行IP封锁,也就是说,GFW直接拦截带有某个IP头的数据包。所以,假如你更改的某域名对应的那个IP被封锁了,即便你过了DNS这一关,也仍旧不能翻过GFW。


这就是为什么hosts的IP时不时update的原因。


Linux装完后,系统自带的hosts文件内容如下:

127.0.0.1    localhost  
127.0.1.1    pangolin  
  
# The following lines are desirable for IPv6 capable hosts  
::1     ip6-localhost ip6-loopback  
fe00::0 ip6-localnet  
ff00::0 ip6-mcastprefix  
ff02::1 ip6-allnodes  
ff02::2 ip6-allrouters





二.修改方法:(hosts文件在最后)(注意:修改hosts文件应以追加方式修改(即在文件末尾添加))

(1).Windows:

在Windows系统里,打开C:\WINDOWS\system32\drivers\etc\hosts文件,在末尾添加如下内容,然后重启电脑即可,腾讯管家、360卫士、金山卫士可能会提示病毒或非法修改系统,请不必理会,并将Hosts文件加入白名单。

(2).linux:

hosts位置不同而已,hosts文件在/etc/hosts,用文本编辑器进入hosts文件即可:如:

vim /etc/hosts

PS:注意要在root权限下才能修改。

(3).其它操作系统:

安卓(Android)手机系统的hosts文件在:system\etc\目录下;Mac和linux一样。





.修改完毕后:

修改完毕后应该刷新 DNS 缓存。

刷新DNS缓存方法:

Windows: 按下 Windows+R 键,运行 cmd ,运行命令 ipconfig /flushdns(然后关机重启电脑)

linux下: 在终端运行命令:sudo /etc/init.d/networking restart   (linux下好像每次开机后都要运行此命令,至少我的ubantu是这样的)(后来又不用刷新了,哈哈)

OS X 10.10: 在[应用程序][实用工具][终端]运行命令:

sudo discoveryutil udnsflushcaches
OS X 10.9: 在[应用程序][实用工具][终端]运行命令:

dscacheutil -flushcache; sudo killall -HUP mDNSResponder
OS X 10.7 ~ 10.8: 在[应用程序][实用工具][终端]运行命令 :

sudo killall -HUP mDNSResponder

Android、iOS: 重新启动设备
