Good morning,
with www.acer.it I have the same problem as swupdl.adobe.com
NXDOMAIN with bind 9.10 but NOERROR with Google DNS
I have read the Mark Andrews reply on july 4 2014:
------------------------------------------------------------------
It looks like nameserver vendors are not doing even rudimentry checks like
those above. DiG has thos options so that we could perform checks like
these.
Until Adobe fix their broken servers you can use a server clause to disable
sending SIT requests to them. Obviously this does not scale.
server <address> { request-sit no; };
Mark
------------------------------------------------------------------
But this doesn't solve the problem on others domains .
. should be possible enable "request-sit no" for all domains and not
manually add it?
Because I think there are lot of domains with this problem L
