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-existence 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signatures were out of date and so on.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.
