Get hostname and ip address of local computer

This code will get the host name and ip for the computer on which the code is run. This works in Visual C++ 5 SP1/2 on NT4 and 95.


#include <winsock2.h>

Link with Wsock32.lib

That's It.
      WORD wVersionRequested;
      WSADATA wsaData;
      char name[255];
      CString ip;
      PHOSTENT hostinfo;
      wVersionRequested = MAKEWORD( 2, 0 );

      if ( WSAStartup( wVersionRequested, &wsaData ) == 0 )

            if( gethostname ( name, sizeof(name)) == 0)
                  if((hostinfo = gethostbyname(name)) != NULL)
                        ip = inet_ntoa (*(struct in_addr *)*hostinfo->h_addr_list);
            WSACleanup( );
