Subject: DNAME [4.6]: Signaling of DNAME Understanding

Issue [4.6]:
   Some mechanism to signal that CNAMEs need not be synthesized.  Also
   signal that DNAME target compression can be used (if RDATA target
   name compression is allowed at all).  EDNS version seems the most
   obvious, states the rfc.  The gain is compression of the DNAME rname,
   and smaller response size.

The original draft says that 'EDNS version 1 signals DNAME compression',
but edns1 has not been defined yet.

Best regards,
   Wouter
