Attributes
address prefix required,immutable
Identifies a prefix (subnet) that an interface belongs to using the
high-order bits of an IPv6 address.

random=5, best-fit=6) default = reservation,extension,random,best-fit
Controls the algorithms used by the server to select a new address
or prefix to lease to a client. The available algorithms are:
client-request
This setting (off by default) controls whether the server
uses a client requested lease.
reservation
This setting (on by default) controls whether the server
uses an available reservation for the client.
extension
This setting (on by default) controls whether the server calls
extensions attached at the generate-lease extension point
to generate an address or prefix for the client.
interface-identifier
This setting (off by default) controls whether the server uses
the interface-identifier from the client's (link-local)
address to generate an address. It is ignored for temporary
addresses and prefix delegation.
random
This setting (on by default) controls whether the server
generates an address using an RFC 3041-like algorithm. It is
is ignored for prefix delegation.
best-fit
This setting (on by default) controls whether the server will
delegate the first, best-fit available prefix. It is ignored
for addresses.
When the server needs an address to assign to a client, it
processes the flags in the following order: client-request,
reservation, extension, interface-identifier, and random.
Processing stops when a usable address is produced.
When the server needs to delegate a prefix to a client, it
processes the flags in the following order: client-request,
reservation, extension, best-fit. Processing stops when a
usable prefix is produced.
