IIS IP binding

If IIS7 does not listen the incoming connections trying to be made to a particular IP address,
even if the binding is set up correctly, check the output of the following command:
netsh http show iplisten

The IP address must be in the list to respond the requests.

To add an IP, type in the following command:
netsh http add iplisten x.x.x.x

It seems, that data is stored in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP\Parameters
