*zone*, a ``dns.name.Name`` or ``text``, the zone which is being
updated.
*rdclass*, an ``int`` or ``text``, the class of the zone.
*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.
*keyalgorithm*, a ``dns.name.Name``, the TSIG algorithm to use.
