利用的是系统里面的hosts文件
Step1:进入Windows目录
C:\Windows\System32\drivers\etc
或者Winnt/System32/Drivers/Etc(Win2K),
C:\Winnt\System32\drivers\etc
找到这个文件夹里面的hosts文件(没有后缀).
Step2:右键点该文件,选择打开方式,选择记事本,大致内容应该如下:
# 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
Step3:添加你要禁止的网站,例如你要禁止3721的网站
则输入(#号代表忽略该行)
#禁止3721.随便写的
127.0.0.1 www.3721.com
然后保存为hosts即可.注意,一定不能有后缀!!!
