使用ipv6调用CoCreateInstanceEx

我试图通过传递ipv6地址来调用CoCreateInstanceEx,但由于访问被拒绝而失败。有办法解决这个问题吗,还是不支持?这是一把狙击枪:

       COSERVERINFO serverinfo;
        ZeroMemory( &serverinfo, sizeof serverinfo);
        serverinfo.pwszName = (OLECHAR *)sAddress.c_str();
        MULTI_QI qi[2];
        qi[0].pIID = &IID_IUnknown;
        qi[0].pItf = NULL;
        qi[0].hr = S_OK;
        qi[1].pIID = &IID_IXSMyIniitialize;
        qi[1].pItf = NULL;
        qi[1].hr = S_OK;
        HRESULT hr = CoCreateInstanceEx( 
            CLSID_CoSMyCOM, 
            0, 
            CLSCTX_LOCAL_SERVER | CLSCTX_REMOTE_SERVER,
            &serverinfo,
            2,
            qi);

如果sAddress类似于10.7.10.10,则有效。但是,如果是fe90::a877:d1aa:43f7:5922这样的话,我会被拒绝访问。两个地址都指向同一服务器。谢谢
