gethostbyname
或对自己连上的socket 查看返回的连接地址

::HOSTENT *htInf = ::gethostbyname( getHostName().c_str() );
std::ostringstream ostr;
if( !htInf )
{
ostr << "Window Sockets error: " << ::WSAGetLastError();
throw ostr.str();
}
::HOSTENT hostInf;
::RtlMoveMemory( &hostInf, htInf, sizeof( hostInf ) );
unsigned char chIP[4]; //每个单元存放的字符的数值分别为4位IP地址的值
unsigned char *pIPList;
::RtlMoveMemory( &pIPList, hostInf.h_addr_list, sizeof( pIPList ) );
::RtlMoveMemory( chIP, pIPList, hostInf.h_length );

for( int i = 0; i < hostInf.h_length; ++i )
ostr << int( chIP[i] ) << ".";

string strIP( ostr.str() );
strIP.erase( strIP.end() - 1 ); //去掉最后一个'.'
return strIP;

这是以前写的一个类中的成员函数，没包括
::WSAStartup( MAKEWORD( 2, 0 ), &_wsaData );
::WSACleanup();
