In further support of preserving sibling records when target chasing comes back negative, I'd like to further explore my offhand mention of "A and/or records". For a domain owner wanting to use a currently IPv4-only service provider (names withheld) while still supporting IPv6, the

Well given that the actual rule is all the algorithms listed in the DS RRset rather than DNSKEY RRset and is designed to ensure that there is always a signature present for each of the algorithms that could be used be used to declare that the child zone is treated as secure, the answer is NO.

Hi - I had someone ask me (last night!!) whether or not the "must sign each RRSet with all of the algorithms in the DNSKEY RRSet" rule applies if the only key with algorithm A in the RRSet has the revoke bit set.  A question I had never previously considered. Given that you can't trace
