how to make bonjour working on windows 7 to discover devices with ipv6 only?

I am working on a project with Windows 7 which discovers some devices with both ipv4 and ipv6. I have tried bonjour sdk which is very convenient, however I don't know if that support ipv6 as I see nothing ipv6 mdns request from wireshark. Does anyone know how to configure it to let it work?
