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.
@ivar qname: The query name
@type qname: dns.name.Name object
@ivar rdtype: The query type

@ivar rdclass: The query class

@param keyname: The name of the TSIG key to use; defaults to None.
The key must be defined in the keyring. 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.

versions which use dnspython's resolver.
This can be useful in testing situations where you want to control
the resolution behavior of python code without having to change
the system's resolver settings (e.g. /etc/resolv.conf).
The resolver to use may be specified; if it's not, the default
resolver will be used.
