help on strange dig info
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.

Those are lame servers, kind sir. In other words, the domain is delegated to those servers but those servers don't recognize their authority.
