HOSTS是什么|HOSTS文件位置|HOSTS文件內容

    HOSTS是一個ASCII碼格式的域名解文件，存儲在：C:\WINDOWS\system32\drivers\etc文件夾下。它里面可以存儲域名到IP地址的映射記錄。在以前沒有DNS服務器進行域名解析的時候就用HOSTS文件來存儲解析記錄，現在也用它存儲一些常用的DNS解析記錄。當然它也有可能被一些惡意網站篡改，當然打開某些網址的時候確打開了另一個網站，就是這種情況。

    HOSTS文件可以用記事本打開，大體內容如下：

# Copyright (c) 1993-1999 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

127.0.0.1       localhost

如果您的HOSTS自己沒有配置過，而與這里的內容不同，有可能被別的程序或病毒、木馬修改過，建議將不同的地方刪除，以免您正常使用電腦。
