Uh? Other addresses *are* trackable, that's the whole point.

The addresses I have right now:

Only the privacy address is not trackable. The other two have fixed
lower 64 bits.

I think Pål's request makes a lot of sense for host candidates.
Server-reflexive and relayed candidates don't matter as they are not
trackable. Asking a TURN server to use a temporary address doesn't make
sense either IMHO.

Therefore, proposed text:

If one or more host candidates corresponding to IPv6 privacy addresses
are advertised, host candidates corresponding to other kinds of IPv6
addresses on the same interface MUST NOT be advertised.
