- You can have only one active connection request per process. Therefore,
all sockets will be automatically bound to this interface. So just use API
you want to use (e. g. WinSock or WinInet) and don't worry about the
underlying interface.
- There is no a supported way to get an IP address of the current interface
before you tried to connect a socket.
- In most cases, you don't need to specify detailed connection requirements,
so the Connection Planner can use default requirements to establish a
connection.
