Hello List,

I have a local recursive resolver based on unbound.

I would like to perform "reverse nxdomain-highjacking". I have defined
an existing domain I would like to block as a local zone.
Currently, I reply with a local IP for those zones. But I would like to
reply with NXDOMAIN.

How can I achieve that in unbound? There is no hint on this in the

I know this is probably not an intended use-case, but if there is a way,
I would appreciate it.
