PowerShell如何使用Windows方法将名称解析到IP地址

Question

我看到有人在使用此操作：

[Net.DNS]::GetHostEntry("serverName").addressList[0].IPAddressToString

...这对我有用。除了，如果我在主机文件中有条目怎么办？这是否使用Windows使用或跳过DNS缓存和主机文件并始终查询DNS服务器的方法？我想使用Windows用于浏览器，Windows Explorer，Ping等的任何方法。

为什么不只是使用内置DNS cmdlet？还是您沿RAW .NET路径行驶的特殊原因？代码项目，家庭作业，好奇心？

# 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.
