when you ask for ANY with a client with rd flag it doesn't provide a
records with cridibilityy level 'glue', it returnsI believe only
'answer' and 'authanswer' credibility, my point is how come the glue
from the parent is considered as a 'answer' credibility in the mentioned
case.
I have a sample domain ladislav.name.ae it has 5 fake unreachable
nameservers, there is no way you can get them with rd flag using ANY or
NS type, since they are in the cache only as a glue.
This seemed confusing to me, how come the answer from the parent is
sometimes considered answer and sometimes as a glue? Does it depend on
the rr type is NS records a different ?
