The IPv6 addresses you're seeing are not "private" — they're <a href="http://tools.ietf.org/html/rfc4193" rel="nofollow">unique local addresses</a>. The DNS magic is just for managing the tunnel endpoints. Once the tunnel is established, it's IPv6 end to end. The tunnel is straight IPv6 over ESP over UDP over IPv4.

Ran some quick tests on my local machine (I’ve been experimenting with “back to my mac” mostly for screensharing use to test GUI Apps)
- Since back to my mac is sometimes down or not supported on a network configuration (won’t work with my network setup in Boston), realizing it’s ipv6 now lets me check whether I have a route with ping6 - thanks.
- I haven’t been able to get traceroute6 to output any info other than numbers of hops, I’d be interested if you have any options that work well for showing more network info
- an nslookup of my gives a result like (not my actual ip, but close enough):
Server: 68.87.100.132
Address: 68.87.100.132#53

Where 53 is the persistent open port for back-to-my-mac and the dnsresult is from the wan-bonjour described in the article.

This isn’t much, but thought it worth sharing if you hadn’t seen it.
