Re: [Softwires] FW:[Int-area] Stateless IPv4-in-IPv6 experiments && DS-Lite/NAT64 experiments

Hello Yiu,

Yes, some apps break by NAT64. We're going to document it.

	Hi Xiaohong,

	I am personally very interested in the data. Do you also document what may break the applications?

	Thanks,
	Yiu

	We have tested how applications behave when it has both DS-Lite IPv4 and NAT64 IPv6 (but not native IPv6). Firefox, IE, Skype, Google Earth v5.2.1, Live Messenger, uTorrent, BitComet, were on our test list. 

	Despres,regarding your question ( maybe not answering your question exactly as we tested NAT64 IPv6 instead of native IPv6 ), uTorrent v2.2 used IPv6 for login/authentication but IPv4 for the data exchange, for IPv6 peer was not able to talk to IPv4 peer. Although BitComet v1.23 issued both A and AAAA quires, it completely ignored AAAA RR and only used IPv4 for communication.

	Please also see some of other test results below. DS-Lite/NAT64 experiments could be documented if it is of interests. 

	Tested Apps                   IPv4/IPv6 portion

	Firefox (Non-vedio) v3.6.12   All IPv6

	Skype v5.0                    Major IPv6

		Thank you, Xiahong, for sharing this interesting information. 

		In the case of BitComet and uTorrent, I wonder what happens if the host has both A+P IPv4 and IPv6, as opposed to just A+P IPv4.
		Did you try that?

		Regards,
		RD
