Have you tried reading the man pages? See specifically dhcpd.conf.5:
For any IPv6 subnet6 on which addresses will be assigned dynamically,
there must be at least one range6 statement. The range6 statement can
either be the lowest and highest IPv6 addresses in a range6, or use
CIDR notation, specified as ip6-address/bits. All IP addresses in the
range6 should be in the subnet6 in which the range6 statement is
declared.
(stateful, IA_NA)
The temporary variant makes the prefix (by default on 64 bits) avail-
able for temporary (RFC 4941) addresses. A new address per prefix in
the shared network is computed at each request with an IA_TA option.
Release and Confirm ignores temporary addresses.
(stateful, IA_TA)
Any IPv6 addresses given to hosts with fixed-address6 are excluded from
the range6, as are IPv6 addresses on the server itself.
(stateful, fixed)
The prefix6 is the range6 equivalent for Prefix Delegation (RFC 3633).
Prefixes of bits length are assigned between low-address and high-
address.
(prefix delegation, IA_PD)
Also, dhcp-options.5 specifies quite a bit about what IPv6 options are
available.
