Erm, I'm low on coffee and so might be unsane at the moment....

There is no additional section because the name-server that you queried (ns1.dnssafe.cn) doesn't know the addresses for:
ns1.dnssafe.cn
ns2.dnssafe.cn


airnet:.subversion wkumari$ dig +norecurse  ns1.dnssafe.cn  @ns1.dnssafe.cn

but, then again, it does the same thing for, well, anything....

airnet:.subversion wkumari$ dig +norecurse +tcp LaLaLaHappyDays  @ns1.dnssafe.cn
