<div dir="ltr">Hi all, <div><br></div><div style>I saw in previous posts that DNSNameError signifies an 'NXDOMAIN' status and DNSServerError signifies 'SERVFAIL'. However, I am getting a DNSNameError from twisted.names.client.lookupAddress() when I query a hostname that has no A records, but *does have* other records (NS, SOA, etc). </div>

<div><br></div><div><br></div><div>dig is telling me 'status: NOERROR'. Is there an easy way to determine the status of a DNS query from a twisted.names.dns.Message ? I checked the source and it wasn't readily apparent (to me). In my code I'm checking the value of failure.value.__class__.__name__ to determine if an answer is NX or SERVFAIL. Seems like there should be a better way... Here's the code if anybody wants to take a look:</div>
