Forward mapping is AAAA records instead of A:

noon            IN      AAAA    2001:638:a01:2:200:39ff:fe40:409a

Reverse is PTR with nibbles used to seperate things, under the
domain, e.g. in I have:

a. IN      PTR

ipv6calc is useful for making reverse maps:

miyu% ipv6calc -r 2001:638:a01:2:200:39ff:fe40:409a

There are a few other things like A6 records, but I won't claim to
understand them.

um, that information consists of two parts: the network prefix (MSB/left
bits of the address) and the host address (LSB/right bits of the address). 
Network prefix should be assigned via Router Advertisement on the LAN (see
articles in my .sig), host adresses are derived from MAC address.

If you have a properly configured rtadvd running on a LAN, all you need is
ip6mode=autohost and rtsol=yes in /etc/rc.conf and that's it.

Maybe read the two articles in my .sig... :)

Want to get a clue on IPv6 but don't know where to start? Try this:
* Basics ->
* Setup  -> 
Of course with your #1 IPv6 ready operating system ->
