# First network adaptor

# IP address, subnetmask and gateway values should be unicode objects

# Set IP address, subnetmask and default gateway
# Note: EnableStatic() and SetGateways() methods require *lists* of values to be passed

#Here is how to revert to obtaining an IP address automatically (via DHCP):

import wmi

# Obtain network adaptors configurations

nic_configs = wmi.WMI().Win32_NetworkAdapterConfiguration(IPEnabled=True)

# First network adaptor

nic = nic_configs[0]

# Enable DHCP

nic.EnableDHCP()
