    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.  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
    node's name might not be the query name.
