If resolving from a certain IP is not allowed REFUSED (=RCODE 3 instead of RCODE 0) is returned, but dnstls.php interprets it wrongly as NXDOMAIN.

The RCODE needs to be evaluated too (see RFC2929):
https://tools.ietf.org/html/rfc2929#section-2.3

how to reproduce:
php dnstls.php dotns1.aco.net dotns1.aco.net
Host dotns1.aco.net not found: 3(NXDOMAIN)
