*
*The request for this service is a structure containing:
*
* - user: the user name
* - password: his password
* - zone: the name of the zone
* - name: the name of the A record(s)
* - oldaddress (optional): the address of the A record to
* delete or "*" to delete all A records
* for the given name.
* - newaddress (optional): the address of the A record to add.
* - ttl (optional): the TTL of the A record to add.
*
* The return value is the whole zone as text.
*
* Inserts can be performed by leaving "oldaddress" empty.
* Deletes can be performed by leaving "newaddress" empty.
* Updates are performed by giving both old and new addresses.
