Windows系統本地域名配置文件hosts位於目錄C:\Windows\System32\drivers\etc中,其內容大致如下所示：
# 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
這裏，我們向其中添加如下一行記錄，代表將域名vm200.lan指向IP地址223.6.6.6，即

通常情況下，系統盤(C:)中的文件對於普通用戶僅僅有隻讀權限，本地域名配置文件hosts即是如此，如果要編輯文件內容，需要修改文件的權限，以hosts爲例，修改步驟如下圖所示。
修改完成後，可以打開命名行終端用ping命令驗證結果，即
