On rare occasion, a Windows computer will have an auto-generated IP address bound as well as a valid public address bound to the same interface:

$ ipconfig

Under this condition, the 0.0.0.0 address may be returned by get_public_ip_address, causing a reservation to fail. Update the code to return the valid public IP address.
