C # To obtain router external network IP,MAC address implementation Code _c# tutorial

C # Implementation of the acquisition router MAC address, router extranet address. For the router MAC address, it is important to know the user name and password of the router Web management system. As for the access to the router's extranet IP address, you do not need to know the Router Web Management system username and password, but need to have a proxy page to obtain the client public network IP address, so that C # request this page can get to the router public IP address. Such as

Getip.ashx

Test route for Mercury MR804, Mercury MR808, can successfully restart Routing and get to router mac and extranet IP address

MFC gets extranet IP address and MAC address

IP address access:

CString Getsystemip (void) {CString cssource; 
 CString csaddress; 
 CString csipaddress; 
 Csipaddress.format (_t ("")); 
 CInternetSession mysession (null,0);

  Display Cssource.format (_t ("%s"), pbuffer); Free (pbuffer); 
  Releases the cache int begin=0;

} return csipaddress;  }

MAC Address acquisition:

CString getmacaddress (void)

 Request memory for Adapter 
 :: GetAdaptersInfo (Adp,&ulong);

 Get local Adapter structure information 
 if (:: GetAdaptersInfo (adp,&ulong) = = ERROR_SUCCESS) 
 { 
  if (ADP!= NULL) 
  { 
   Strmacadd.format ("%s", adp->address); 
   memcpy (pmac,adp->address,6); 
   Strmac.format (_t ("%02x-%02x-%02x-%02x-%02x-%02x"), pmac[0],pmac[1],pmac[2],pmac[3],pmac[4],pmac[5]);
