DNS problem, CNAME not recursively resolving

fortran01 · 03-03-2008, 02:04 PM

I am using mydns.

I have the following CNAME record:

Code:

mail  	CNAME  	ghs.google.com.  	0  	86400

If I do a dig, I can see that ghs.google.com is not resolving properly to its A record.

Code:

# dig mail.test.net

; <<>> DiG 9.4.1-P1 <<>> mail.test.net
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2884
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;mail.test.net.         IN      A

;; ANSWER SECTION:
mail.test.net.  86400   IN      CNAME   ghs.google.com.

The ideal situation would be something like this (observe how www.l.google.com is resolved):

Code:

# dig www.google.com

; <<>> DiG 9.4.1-P1 <<>> www.google.com
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 45264
;; flags: qr rd ra; QUERY: 1, ANSWER: 5, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;www.google.com.                        IN      A

;; ANSWER SECTION:
www.google.com.         594172  IN      CNAME   www.l.google.com.
www.l.google.com.       146     IN      A       74.125.19.104
www.l.google.com.       146     IN      A       74.125.19.147
www.l.google.com.       146     IN      A       74.125.19.99
www.l.google.com.       146     IN      A       74.125.19.103

TIA!
