It is a shame. I have a zone already created and inside this zone I
Need to create A entries pointing to the same ip address. 

Example:

test001 IN A 127.0.0.1
test002 IN A 127.0.0.1
test003 IN A 127.0.0.1
...
testN	  IN A 127.0.0.1

N is a number between 001 and 999.

Thank you!

No. Not possible in BIND. The DNS protocol defines a wildcard mechanism, 
but it only matches 1 or more whole labels.

Of course, you could always just put 1 or more wildcard records into 
"domain" itself and not have any subzones. The wildcard would match the 
name "test001.domain" and anything else under "domain" that wasn't 
already explicitly defined.

I know of no such patch.
