Windows系统hosts位于 C:\Windows\System32\drivers\etc\hosts
Android（安卓）系统hosts位于 /system/etc/hosts
Mac（苹果电脑）系统hosts跟Linux一样位于 /etc/hosts
iPhone（iOS）系统hosts跟Linux Mac一样位于 /etc/hosts
Linux系统hosts位于 /etc/hosts
注意：hosts文件属于系统核心文件之一，所以Windows用户必须用***身份打开才能修改保存，如果遇到无法保存，请右键文件hosts并找到“属性” -> “安全”，然后选择你登陆的用户名，最后点击编辑，勾选“写入”即可。
注意*2：hosts被修改可能导致系统异常，博主搞Linux时手滑删了hosts，结果系统变得非常非常卡，经常找不到主机“debian”
Android（安卓）必须Root才能修改，Root Explorer管理器或ES文件浏览器装载/system可写状态，找到/system/etc/hosts的文件，使用文本编辑器打开编辑后保存。
Linux系统使用Root权限vi编辑
而iPhone、iPad也必须越狱才能修改！Windows系统跟苹果系统的hosts文件文本编码和换行符格式一样，而Android（安卓）则不一样，这点你需要注意。
windows：
# 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
Mac、iPhone、iPad原版hosts文件：
## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::10 localhost
Linux系列我就不列出了，因为每个繁生版本都不一样，而且用Linux的人一般不是小白。
