I'm looking for tips on how to implement CNAME Flattening in PowerDNS . I believe other DNS providers accomplish this using so-called "ANAME" records.
I assume it involves the use of ALIAS records and found this comment in another thread: Starting with the PowerDNS Authoritative Server 4.0.0, DNSSEC ‘washing’ of ALIAS records is supported on AXFR (*not* on live-signing). Set outgoing-axfr-expand-alias to ‘yes’ and enable DNSSEC for the zone on the master. PowerDNS will sign the A/AAAA records during the AXFR. Does this accomplish CNAME Flattening vis-a-vis the intended ANAME behavior or is there more to it? thanks in advance, Tom
