Re: Request for Comments on Internet Draft about IoT DNS Name Autoconf

[manning <[e-mail]>]

The reason I ask is that the title is about DNS name autoconfig.  It might be reasonable to run a parallel stream in DNSOPs, in the unlikely event of problems.

If the point of the effort is autoconfiguration, relying on out-of-band configuration for this  seems contrary to the goal.  If you distribute the decryption keys within the DNS, however, you are likely to lose whatever privacy protection is provided.  Can you explain this further?
