I'm seeing what looks like cached CNAME records overriding addresses set
with --address.
Setup: using a version since 2.86 (I used 2.89) override A records for
an upstream domain with --address but allow other queries for the domain
to be forwarded upstream.
When querying A records for a name that the upstream returns CNAME for,
the response is initially the expected overridden address. However,
after requesting AAAA records and getting a CNAME response, further
queries for A records return the CNAME record.
As long as other record types are not wanted, this can be mitigated by
restoring the previous behavior with --local, as per the manpage.
