[Dnsmasq-discuss] Unexpected caching behavior when using --address

[Dom Sekotill]

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.
