As has been explained already, no answer, no error means that the name exists, but not an RRset of the type you queried for. Since the ANY query also comes back empty, you've probably got a situation something like this in the zone: sample 7200 IN A 192.0.2.53 child.sample 7200 IN A 192.0.2.54 * 7200 IN A 192.0.2.101 If you delete the 'sample' RR, the wildcard will still not match any queries for sample. This is because the existence of 'child.sample' means that 'sample' also exists, even though it has no RRsets of any type. 'sample' in this case is what's called an 'Empty Non-Terminal'. Does this scenario explain what you are seeing?
