Unbound module documentation ================================ .. automodule:: unbound Class ub_ctx -------------- .. autoclass:: ub_ctx :members: :undoc-members: .. automethod:: __init__ Class ub_result ---------------------- .. autoclass:: ub_result :members: .. attribute:: qname The original question, name text string. .. attribute:: qtype The class asked for. .. attribute:: canonname Canonical name for the result (the final cname). May be empty if no canonical name exists. .. attribute:: answer_packet The DNS answer packet. Network formatted. Can contain DNSSEC types. .. attribute:: havedata If there is any data, this property is true. If false, there was no data (nxdomain may be true, rcode can be set). .. attribute:: secure True, if the result is validated securely. False, if validation failed or domain queried has no security info. It is possible to get a result with no data (havedata is false), and secure is true. This means that the non-existance of the data was cryptographically proven (with signatures). .. attribute:: bogus If the result was not secure (secure==0), and this result is due to a security failure, bogus is true. This means the data has been actively tampered with, signatures failed, expected signatures were not present, timestamps on signatures were out of date and so on. If secure==0 and bogus==0, this can happen if the data is not secure because security is disabled for that domain name. This means the data is from a domain where data is not signed. .. attribute:: nxdomain If there was no data, and the domain did not exist, this is true. If it is false, and there was no data, then the domain name is purported to exist, but the requested data type is not available. .. attribute:: rcode DNS RCODE for the result. May contain additional error code if there was no data due to an error. 0 (RCODE_NOERROR) if okay. See predefined `RCODE_` constants. RCODE can be represented in display representation form (string) using :attr:`rcode_str` attribute.
