"""
Class for parsing the file ``/etc/named.conf```, We use class ``NamedCheckConf`` to parse most
of the named.conf configurations and class ``NamedConf`` to parse the `include` directives and
the `allow-recursion` values.
.. note::
Please refer to the super-class :py:class:`insights.parsers.named_checkconf:NamedCheckConf`
for more usage information.
Attributes:
includes (list): List of files in 'include' section.
allow_recursion_address (list): List of address in 'allow-recursion' section.
Raises:
SkipComponent: When content is empty or cannot be parsed.
Examples:
>>> named_conf.includes
['/etc/crypto-policies/back-ends/bind.config']
>>> named_conf.allow_recursion_address
['localnets', 'localhost', '192.168.10.1/24']
