Initialize a new DNS Update object. See the documentation of the Message class for a complete description of the keyring dictionary. *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.

Add records. *replace* is the replacement mode. If ``False``, RRs are added to an existing RRset; if ``True``, the RRset is replaced with the specified contents. The second argument is the section to add to. The third argument is always a name. The other arguments can be:

Replace records. The first argument is always a name. The other arguments can be:
Note that if you want to replace the entire node, you should do a delete of the name followed by one or more calls to add. |
Require that an owner name (and optionally an rdata type, or specific rdataset) exists as a prerequisite to the execution of the update. The first argument is always a name. The other arguments can be:

Return a string containing the update in DNS compressed wire format. *origin*, a ``dns.name.Name`` or ``None``, the origin to be appended to any relative names. If *origin* is ``None``, then the origin of the ``dns.update.Update`` message object is used (i.e. the *zone* parameter passed when the Update object was created). *max_size*, an ``int``, the maximum size of the wire format output; default is 0, which means "the message's request payload, if nonzero, or 65535". Returns a ``binary``.
