any IA of any clients will be able get this address prefix. At most eight static binding address prefix can be configured

for each address pool. For prefix delegation, static binding is of higher priority than the prefix address pool.

The following command will allocate 2001:da8::/48 to the client with DUID as 0001000600000005000BBFAA2408,

and IAID as 12.
