Hello,

I digged a domain name as below:

r...@dev1:~# dig www.csfunds.com.cn

; <<>> DiG 9.5.0-P2 <<>> www.csfunds.com.cn
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 23283
;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 2, ADDITIONAL: 0

;; QUESTION SECTION:
;www.csfunds.com.cn.            IN      A

;; ANSWER SECTION:
www.csfunds.com.cn.     86149   IN      CNAME   www.f5.csfunds.com.cn.
www.f5.csfunds.com.cn.  30      IN      A       124.207.40.24

;; AUTHORITY SECTION:
f5.csfunds.com.cn.      85769   IN      NS      lc2.f5.csfunds.com.cn.
f5.csfunds.com.cn.      85769   IN      NS      lc1.f5.csfunds.com.cn.


It said f5.csfunds.com.cn's nameservers are lc1.f5.csfunds.com.cn and 
lc2.f5.csfunds.com.cn.


But, I can't dig the info for both lc1 and lc2.

r...@dev1:~# dig lc1.f5.csfunds.com.cn

; <<>> DiG 9.5.0-P2 <<>> lc1.f5.csfunds.com.cn
;; global options:  printcmd

r...@dev1:~# dig lc2.f5.csfunds.com.cn

This let me really confused.
When clients can't get IP addr for lc1 and lc2, how clients query the domain 
records in zone of f5.csfunds.com.cn?

Thanks for your helps.

Regards.
Ken.
