How to get IP Address from Registry ?

NTDEV
1

Hello all :

Currently, I know the following registry entries correspond to the IP
configuration of the network address¡G
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services%NIC%\Parameters\Tcpip]
Where NIC means the service key for the network adapter.

However, I can not figure out how to get those “service keys” in order
to get the corresponding IP Address.

I am using RtlQueryRegistryValues now. But I can not make it enumerate
all stuffs under CurrentControlSet\Services …

Any suggestion ?

IP addresses are in

Services\Tcpip\Parameters\Interfaces{GUID}

This is exactly the subkey which can be accessed by
NdisOpenProtocolConfiguration.

What are you trying to accomplish? I can only assume that you wish to get the IP address of some interface, or any interface. If you were, for instance, to ask the question “How do I get the IP addresses assigned to a particular NIC from within an IM driver bound to that NIC” you might get a really good answer. Just asking how to wander around the registry looking at TCPIP’s private registry settings may not get you the answer you need.

Look at OID_GEN_NETWORK_LAYER_ADDRESSES. Alternatively, you can do a bunch of work with TDI to find the IP addresses that correspond to the interface with the L2 MAC address of the NIC of interest.

Good Luck,
