comment Why do authoritative and cached names servers return different records for ANY type?
Thanks, this is helpful, although it doesn't explain why specifically asking the cache for the "missing" records, and then immediately requesting ANY doesn't seem to help. Why doesn't the cache get populated in this case?

This might be related to ANY being involved in attacks on internet infrastructure: blog.cloudflare.com/deprecating-dns-any-meta-query-type datatracker.ietf.org/doc/draft-ietf-dnsop-refuse-any/… The authoritative servers seem to support ANY though, it's just the caches that don't.
