Hello all, I am running Bind 9.7.1-p2 as recursive dns. I encountered this problem with the domain hsbc.com.bd. When I dig hsbc.com.bd, it gives me a connection timed out response.
#dig hsbc.com.bd ; <<>> DiG 9.7.1-P2 <<>> hsbc.com.bd ;; global options: +cmd ;; connection timed out; no servers could be reached But when I cleared my cache thru rndc flush, I then have a response and solved the problem: #dig hsbc.com.bd ; <<>> DiG 9.7.1-P2 <<>> hsbc.com.bd ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 10733 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 3 ;; QUESTION SECTION: ;hsbc.com.bd.

I found out that if I clear the cache and then dig first the ns record(s) of com.bd, before I dig hsbc.com.bd, I will be able to replicate the problem. What bothered me is what is in com.bd that blocks the response from hsbc.com.bd? Please I need your inputs. Thanks, Bangla
