Instances of this class bundle up the result of a successful DNS
resolution.
For convenience, the answer object implements much of the sequence
protocol, forwarding to its ``rrset`` attribute. E.g.
``for a in answer`` is equivalent to ``for a in answer.rrset``.
``answer[i]`` is equivalent to ``answer.rrset[i]``, and
``answer[i:j]`` is equivalent to ``answer.rrset[i:j]``.
Note that CNAMEs or DNAMEs in the response may mean that answer
RRset's name might not be the query name.

The *qname*, *rdtype*, and *rdclass* parameters may be objects
of the appropriate type, or strings that can be converted into objects
of the appropriate type.
*qname*, a ``dns.name.Name`` or ``text``, the query name.
*rdtype*, an ``int`` or ``text``, the query type.
*rdclass*, an ``int`` or ``text``, the query class.
*tcp*, a ``bool``. If ``True``, use TCP to make the query.
*source*, a ``text`` or ``None``. If not ``None``, bind to this IP
address when making queries.
*raise_on_no_answer*, a ``bool``. If ``True``, raise
``dns.resolver.NoAnswer`` if there's no answer to the question.
*source_port*, an ``int``, the port from which to send the message.
*lifetime*, a ``float``, how long query should run before timing out.
Raises ``dns.exception.Timeout`` if no answers could be found
in the specified lifetime.
Raises ``dns.resolver.NXDOMAIN`` if the query name does not exist.
Raises ``dns.resolver.YXDOMAIN`` if the query name is too long after
DNAME substitution.
Raises ``dns.resolver.NoAnswer`` if *raise_on_no_answer* is
``True`` and the query name exists but has no RRset of the
desired type and class.
Raises ``dns.resolver.NoNameservers`` if no non-broken
nameservers are available to answer the question.
Returns a ``dns.resolver.Answer`` instance.

See the documentation of the Message class for a complete
description of the keyring dictionary.
*keyring*, a ``dict``, the TSIG keyring to use. If a
*keyring* is specified but a *keyname* is not, then the key
used will be the first key in the *keyring*. Note that the
order of keys in a dictionary is not defined, so applications
should supply a keyname when a keyring is used, unless they
know the keyring contains only one key.
*keyname*, a ``dns.name.Name`` or ``None``, the name of the TSIG key
to use; defaults to ``None``. The key must be defined in the keyring.
*algorithm*, a ``dns.name.Name``, the TSIG algorithm to use.

*edns*, an ``int``, is the EDNS level to use. Specifying
``None``, ``False``, or ``-1`` means "do not use EDNS", and in this case
the other parameters are ignored. Specifying ``True`` is
equivalent to specifying 0, i.e. "use EDNS0".
*ednsflags*, an ``int``, the EDNS flag values.
*payload*, an ``int``, is the EDNS sender's payload field, which is the
maximum size of UDP datagram the sender can handle. I.e. how big
a response to this message can be.
