Hi,
I do not use a CNAME for our NS, but our secondary (slave) server that
we do not manage (different company) has it :-/.
I've asked the administrator today's morning, so we will see.
Thanks and best regards

  ISC bind is strict about CNAME of NS server:

 How about Knot resolver ? 
 Hello.  I believe there is neither effort to disallow them nor to make
 them work.  Off the top of my head I'm not sure how it will be in
 practice; you could just try.  Either way, please don't use them.
