Clarification on bind result

[rams]

Hi ,

I have the following zone file:

$ORIGIN td3497.com.

@ IN SOA udns1.ultradns.net. ppk.yahoo.com. (

2010052610 ; serial

10800 ; refresh

3600 ; retry

2592000 ; expire

86400 ; minimum

)

cname.chain.td3497.com. 86400 IN CNAME mx.chain.td3497.com.

mx.chain.td3497.com. 86400 IN MX 34 mx1.chain.td3497.com.

mx1.chain.td3497.com. 86400 IN MX 34 mx2.chain.td3497.com.

mx2.chain.td3497.com. 86400 IN MX 34 mx3.chain.td3497.com.

mx3.chain.td3497.com. 86400 IN A 1.2.3.4

ramesh.td3497.com. 86400 MX 20 .

ramesh.td3497.com. 86400 MX 20 mx1.

*cname.td3497.com. 86400 CNAME .*

 td3497.com. 86400 IN NS udns2.ultradns.net.

td3497.com. 86400 IN NS udns1.ultradns.net.

;End



I queried for cname domain against bind 9.6.X and got the following response

C:\Documents and Settings\rameshb>dig @localhost cname.td3497.com mx

; <<>> DiG 9.6.1-P1 <<>> @localhost cname.td3497.com mx
; (1 server found)

Here why authority section is not returned? Actually authority section
should be returned with SOA right?

Thanks & Regards,

Ramesh
