SUMMARY

The IP address assigned to a RAS client is obtained by the client program using the RasGetProjectionInfo API. You call this API after a RAS connection has been established.

MORE INFORMATION

If your program is using the RasDial API to establish a RAS connection, the following code demonstrates printing out the IP address assigned to your client by the RAS server:

if (!RasDial(NULL, NULL, &MyRasdialParams, 0L, NULL, &hRasConn)) 

   {
   cb = sizeof(proj_buf);
   proj_buf.dwSize = cb;
   if (!RasGetProjectionInfo(hRasConn, RASP_PppIp, (LPVOID)&proj_buf, &cb))
      printf("Client ip addr is %s\n",  proj_buf.szIpAddress);
   }
If your program did not establish the RAS connection, you need to call the RasEnumConnections API to obtain a list of RAS connections already established on your client machine. From this list of existing RAS connections, you can obtain a RAS connection handle that you can then pass into RasGetProjectionInfo (as the first parameter).
