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 ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 29538 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;lc1.f5.csfunds.com.cn.

IN A 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.
