I am not able to wrap my head around the fact that an automatically
generated addressing system could be used as static addresses for
publishing services (via DNS).
I guess, the best way to get a feel for this is to try implementing ip6 on
a system or a subnet and see how the ip6 provides hooks between address
generation and publication of routes to the generated addresses. I do hope
to get to this one of these days!
