If it's static ip, what's the exact value?

How to use python get my windows box's ip setting type? Dynamic ip, or
static ip?

If it's static ip, what's the exact value?

Here's one way:

def ipinfo(interface="Local Area Connection"):
dhcpenabled = False
staticip = None
subnetmask = None
for l in os.popen('netsh interface ip show address "%s"' % interface):
l = l.strip()
if l.startswith('DHCP enabled'):
dhcpenabled = l.endswith('Yes')
if l.startswith("IP Address"):
staticip = l.rsplit(None,1)[-1]
if l.startswith("SubnetMask"):
subnetmask = l.rsplit(None,1)[-1]
return dhcpenabled, staticip, subnetmask
(False, '192.168.126.1', '255.255.255.0')

The way has one shortcoming. That's it depend on the proper language
version of Windows. If I'm using Simplified Chinese Windows, I must
modify some strings.

You can use WMI to list properties of your network adapter(s):
import win32com.client
wmi=win32com.client.GetObject('winmgmts:')
adapters=wmi.InstancesOf('Win32_NetworkAdapterConfiguration')
for adapter in adapters:
print adapter.Properties_['Caption'], adapter.Properties_['DhcpEnabled'], adapter.Properties_['IpAddress']

There are some errors in result:.... print adapter.Properties_['Caption'],
adapter.Properties_['DhcpEnabled'], adapter.Properties_['IpAddress']
....

return str(self.__call__())

How to deal with it?

This means the unicode object contains characters that
can't be represented in the default encoding. Try encoding it
in another character set, something like

adapter.Properties_['Caption'].Value.encode('mbcs')
(you may need to use a different codec)

Thank you very much.

Does the wmi object can modify the ip address?
