懒人Win10专业版系统hosts文件怎么修改？

　　2、以文本的方式打开hosts文件之后，原始的hosts文件内容如下：

# Copyright （c） 1993-2009 Microsoft Corp.

#

# This is a sample HOSTS file used by Microsoft TCPIP 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

# 38.25.630 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.

# 127.0.0 localhost

# ：：1 localhost
