Just curious, you put the actual TLSA record first and then the
CNAMEs. Any particular reason for the order?
Clarity of exposition. You're outsourcing thinking about this to
the list.
No, I had thought about this and had come to the conclusion that
order did not make a difference (as per below).
* A DNS zone is a key-value database:
(owner-name, class, type) => RRset
* As with any key-value database the relative order
of keys cannot be significant.
* Even the relative order of RRs within an RRset is not significant
for DNSSEC purposes, as the RRset signature is calculated over
the canonical ordering. So RRsets in which the order matters
cannot rely on DNSSEC to protect that order.
Take care
