I understand the unbound purpose, as a recursive dns server.
Unbound has auth-zone but doesn't act as fully authoritative?
As the doc:
- for-downstream: yes, and when used in this manner make unbound respond
like an authority server.
If I understand right and want to be fully authoritative I need NSD or
I read some parts of the code to understand more.
I have used the same zone in unbound and NSD, and they reply the same way.
If unbound downloads the zone using http without authentication,
And can download the zone receiving XFR replies, why just don't reply to
Even an AXFR (without IXFR).
Since the first unbound was released, it has grown.
Is there a bigger reason, or is it just because unbound will always be
focused on a recursive server?
I don't want to need to run another daemon with other dependencies, to do
something that is already partially done.
That means having another, totally separate control.
If it's not and will not become possible (even if someone coded that, PR),
It's just, I really wanted to know if there was a specific reason, as most
of the features are already there.
Thanks a lot for the reply.
