PowerDNS fields

domains
A list of domains served


 * id
 * Database-internal, just an index


 * name
 * The domain name, for sure


 * master
 * A string. I don't know?


 * last_check
 * Dunno


 * type
 * Master, slave, super-slave


 * notified_serial
 * Presumably just the serial?


 * account
 * Dunno

records
A resource record (that's the correct term, right?)


 * id
 * Database-internal, just an index


 * domain_id
 * Database index of the domain


 * name
 * Record name


 * type
 * I'm guessing the RR-type? A, AAAA, TXT, etc?  It's a 6-char string, which supports that supposition


 * content
 * Value of the record


 * ttl
 * Time-to-live, clearly. But per-record?  Really?


 * prio
 * Priority...? Of what?


 * change_date
 * Date of last change, it would seem

supermasters
WTF is a supermaster?


 * ip
 * The IP of the supermaster, whatever that is


 * nameserver
 * The name of the (primary?) nameserver


 * account
 * Not sure?

Other Notes
Oh, it occurs to me that "account" might be for the benefit of registrars or something? Like an honest-to-goodness account?
