Using BIND-9.18.5 as a recursive server:
What's the reason, that BIND answers with the additional section for the

Any hints why BIND adds the additional section while other resolvers
doesn't? Is there an option in BIND to behave like Knot/PDNS?
The option is "minimal-responses". If you set it to "yes", it will omit
authority and additional section data except when necessary.
The default is "no-auth-recursive", which omits authority section data
when it isn't strictly necessary, but will still add additional data for
records in the answer section.
I've already set "minimal-responses yes;", but the additional
section/data is still shown. So based on your explanation, BIND assumes,
this data is necessary, why? And why behaves BIND different here than
Knot/PDNS where no additional section is shown for the same query?
Does an BIND expert has an idea or an explanation, why the additional
section is still shown, although "minimal-responses yes;" is set? And
why the additional section seems necessary for BIND and not for example
for Knot/PDNS for the same query?
Many thanks for any hints.
Tom
