And what does this has in common with the thread you've replied to?

Looks like rankstel.net is delegated to two nameservers
  (see dig ns rankstel.net @e.gtld-servers.net.):

ns1.ranksitt.net. (which refuses to answer for it) and
ns1.rankstel.net. (which times out).
So, rankkstel.net is broken, you cannot do anything with it.

And era.com.bd is delegated to ns2.ranksitt.net., ns1.ranksitt.net. and 
dns.bankasia.com.bd.
And I see three different answers from those servers. Only 
ns2.ranksitt.net seems to be configured correctly (But I haven't dig any 
deeper).

Note, I've not tested it deeply, so it might be wrong.
