That is the case.

The recent changes seem to be focused on OS X working well when IPv6-only, and the addition of DHCPv6 for DNS resolver discovery was very welcome in Lion.  I was able to run pretty much the whole recent IETF meeting on the IPv6-only SSID, given my university resources (mail, web etc) are available over IPv6, as are the IETF's and many associated sites, and all that is searchable via Google over v6.   Quite a good way to focus on work actually, though Google+ is available over IPv6.

The same applies to iOS and the iPhone, which also has DHCPv6 support.
