You appear to have recursion disallowed on the BIND 9 setup. Note the status: REFUSED and recursion requested by not available.
Also, don't use http:// in your dig queries. I'm surprised that works... or maybe it doesn't which could be confusing things.

Subject: answer to not existing record
Hello,
I have seen a difference in the behaviour for a query to a non existing query (the domain is not manage by the name server) between bind8 and bind9.
I just would like to know if it is normal or if it is a problem.
Thanks in advance for your feedback
