<div dir="ltr"><div>Greetings,</div><div><br></div><div>I'm trying to use the Python module to generate NAPTR responses. Starting with the unmodified resgen.py example script, it correctly responds to A type queries, but when trying NAPTR, it does not work.</div>

<div> #create instance of DNS message (packet) with given parameters</div><div>- msg = DNSMessage(qstate.qinfo.qname_str, RR_TYPE_A, RR_CLASS_IN, PKT_QR | PKT_RA | PKT_AA)</div><div>+ msg = DNSMessage(qstate.qinfo.qname_str, RR_TYPE_NAPTR, RR_CLASS_IN, PKT_QR | PKT_RA | PKT_AA)</div>
