I really want to be able to change the ip address, subnet mask, and default route from my program. I''ve pretty much figured out how to do this under Linux, but would like it to work under NT (at least XP) as well. Does anyone know how you even look-up the subnet mask and default route from code?

Perhaps you could use the following to get some of the information:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Adapters

In there there will be a key for each adapter and will contain an IpConfig value which points to a key in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces

Should give you lots of information about the TCP/IP settings for the adapter.

edit: Perhaps the correct way: IPHelper
