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.

This cache is better than the simple cache (above) if you're
running a web crawler or other process that does a lot of
resolutions. The LRUCache has a maximum number of nodes, and when
it is full, the least-recently used node is removed to make space
for a new one.

All of the "business logic" of resolution is encapsulated in this
class, allowing us to have multiple resolve() implementations
using different I/O schemes without copying all of the
complicated logic.

S |r%q)a� Query nameservers to find the answer to the question.
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 ``str``, the query name.
*rdtype*, an ``int`` or ``str``, the query type.
*rdclass*, an ``int`` or ``str``, the query class.
*tcp*, a ``bool``. If ``True``, use TCP to make the query.
*source*, a ``str`` 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 many seconds a query should run
before timing out.
*search*, a ``bool`` or ``None``, determines whether the
search list configured in the system's resolver configuration
are used for relative names, and whether the resolver's domain
may be added to relative names. The default is ``None``,
which causes the value of the resolver's
``use_search_by_default`` attribute to be used.
Raises ``dns.resolver.LifetimeTimeout`` 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.

raise, other than ``dns.resolver.NoAnswer`` and
``dns.resolver.NXDOMAIN``.
Returns a ``dns.name.Name``.

Resolvers (DDR). If successful, the resolver will subsequently use
DNS-over-HTTPS or DNS-over-TLS for future queries.
*lifetime*, a float, is the maximum time to spend attempting DDR. The default
is 5 seconds.
If the SVCB query is successful and results in a non-empty list of nameservers,
then the resolver's nameservers are set to the returned servers in priority
order.
The current implementation does not use any address hints from the SVCB record,
nor does it resolve addresses for the SCVB target name, rather it assumes that
the bootstrap nameserver will always be one of the addresses and uses it.
A future revision to the code may offer fuller support. The code verifies that
the bootstrap nameserver is in the Subject Alternative Name field of the
TLS certficate.
