W.C.A. Wijngaards via Unbound-users:
My guess is both do not work and the TTL is different.
not impossible ...
Normally, unbound should try both addresses, and I guess it is
trying them but
the other also does not work. unbound-control lookup can be used to
get the info on those two IP addresses, like ping time. Or maybe you
can dig @10.0.1.53 and see if it responds.
Otherwise, this is a bug of some sort, unbound should be trying all
available name servers for your query.
I tried to reproduce the error condition with only one nameserver.
No Error :-/
I'll have to setup a second nameserver I could switch off on demand.
more observation if that's done...
The local-zone config did not seem to be the problem.
was my guess about transparent vs. nodefault right?
Thanks
