PyCharm开发Python利用WMI修改电脑IP、DNS

1.在PyCharm开发中安装WMI插件


搜索需要添加的WM插件，并安装，安装成功后会有提示！

2.源代码：

"""=== coding: UTF8 ==="""

import wmi

# IP地址
arrIPAddresses = ['192.168.30.79']
# 子网掩码
arrSubnetMasks = ['255.255.255.0']
# 默认网关
arrDefaultGateways = ['192.168.30.1']
arrGatewayCostMetrics = [1]
# DNS列表
arrDNS = ['114.114.114.114', '114.114.115.115']
