According to the 4.1.1 dhcp-options man page:
option dhcp6.ia-pd string;
The ia-pd option is manufactured by clients and servers to create a
Prefix Delegation binding - to delegate an IPv6 prefix to the
client. There is not yet any support for prefix delegation in this
software, and this option is provided informationally only.
4.1.1 is latest production release. Perhaps the 4.2.0b1 beta has it.
Also, please post in plain text.
