I suspect Dropbox to hardcode their IP in their application. It's not working at all on ipv6-only.
Yeah, looks like that: furry@Wintermute:~>sudo tcpdump -i en0 -s 1500 -n 'net 64:ff9b::6ca0:0/120 or net 108.160.172.0/24' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en0, link-type EN10MB (Ethernet), capture size 1500 bytes 14:59:48.934365 ARP, Request who-has 108.160.172.193 tell 169.254.64.90, length 28 14:59:49.323255 ARP, Request who-has 108.160.172.204 tell 169.254.64.90, length 28 14:59:50.019231 ARP, Request who-has 108.160.172.193 tell 169.254.64.90, length 28 14:59:50.420251 ARP, Request who-has 108.160.172.204 tell 169.254.64.90, length 28 I'll follow up on this...
On the contrary, I'm pleasantly surprised to see that Cisco DTLS VPN works over NAT64.
Thanks for giving us a sandbox, that is really interesting.
Great to know, thanks for the feedback!

Sorry, a very important part was missed in my email:
Big thanks to Cisco Systems (Eric Vynce, Steve Simlo and Andrew Yourtchenko in particular) for providing with NAT64 solution and to RIPE NCC for building this network and proving that IPv6 does work! IPv6-only network @RIPE would have never happened without their help!
My apologies for not mentioning this in my email in the first place.

I'm glad to announce that there is a IPv6-only (with NAT64) network at RIPE70.
Please note that this experimental network is not supported by the RIPE NCC or RIPE 67 Technical Team and is offered on a best-effort basis.
How to connect:
- Make sure IPv6 is enabled on your device - Connect to SSID: IPV6ONLYEXP - Enter the password: iknowbesteffort
Please note that NAT64&DNS64 is used to provide connectivity to IPv4-only resources, so use DNS servers information provided by the network.
If you see any connectivity issues: - connect to the 'normal' dual-stack one; - if connecting to dual-stack network solves the issue, please email me (furry13@gmail.com) with details, I'd love to know about any problems.
General feedback (do you guys see any value in such an experiment, what was your experience etc) is appreciated.
