zone_id = optional zone id, or use -1 if you do not care about such
things. This is an opaque integer used by powerdns in various places to
tell you which zone it means.

domain_id = ditto above, but for domains

auth = 1 if your data is authoritative for the zone and 0 if not.
usually you should set this to 1. setting it 0 will put the data into
additional section.

scopeMask = how many bits of requestor IP was used to produce this
result. this should 0 unless you are using the client's (real) IP
somehow to come up with the answer, and if you do, how many bits of the
value was used. 128 (v6) or 32 (v4) means you used up the whole IP, 0
means no bits were used.
