[OSX-Users] Fwd: [81attendees] Mac OS X on the "ietf-v6only" network?

[Tim Chown]

Thought you might like this.   

MacOS X Lion running IPv6-only in the IETF v6ONLY wireless network here in Quebec, and me being able to send/read mail with Mac Mail securely using just IPv6.

I can get to all the useful ECS web stuff via v6 only as well, of course, and all the IETF material is v6-enabled.

The key thing Lion has added is improved support for IPv6-only, including at last a DHCPv6 client that can get IPv6 DNS resolver information.
