If the server answers, then it's responding. Then you perform a further check for aa bit, valid SOA RR or whatever you queried for. tinydns, out-of-the-box, does not respond to queries for zones it is not authoritative for. Unnecessarily seperating your tests for responsiveness and authority may be problematic because of this.
