最近搞了个openWrt的路由器，可以配置酸酸乳，配置好之后，发现没法正常的使用 Google，一想，可能是因为很早以前修改了系统的 hosts 文件，(当时这是使用 Google 的一种方法，后来用了小飞机啥的)。然后我去网上找了一段 hosts 的默认内容:

hosts文件路径：C:\WINDOWS\system32\drivers\etc\hosts
以管理员身份运行记事本，再用记事本打开hosts文件才能保存。
我一般都用 notepad++ 编辑。


# 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

替换之后就可以自由的遨游了.
