Clarification on wildcard scenario

[rams]

Hi Mark,

Thank You for quick clarify. I have included trailing dot and restart bind.
Now when i queired for domain "www.joshfeb1.com" with type A, I am getting
NOERROR and NOANSWER.

[root@ zones]# dig  www.joshfeb1.com. A

; <<>> DiG 9.6.1-P3 <<>>  www.joshfeb1.com. A

[root at zones]#

Is it correct. Actually www.joshfeb1.com is not exist and it should look
into *.joshfeb1.com right. Could you please clarify why it is not returning
answer.

Thanks & Regards,
Ramesh
