Hello: I am trying to implement a custom DNS resolver, using the DNS Howto custom resolver as a boiler plate. I have a database-driven cache that I am reading from, but am unsure how to implement a cache ‘miss’ (i.e. NXDOMAIN).
The ‘hit’ is fine, apropos to: answer = dns.RRHeader( name=name, payload=dns.Record_A(address=b’127.0.0.1’)) # for example sake But I tried with dns.Record_NULL to generate an NXDOMAIN-like response without success. How can I implement this? Rob
