Hello All,

I am using version 1.5.0 Kea DHCPv6 version. I have allocated a /64
subnet as below

  "subnet6": [


                "subnet": "fd00:1:dead:beef::/64",

                "id": 1024,

                "interface": "bond0",

                "pools": [

                    { "pool": "fd00:1:dead:beef::15-fd00:1:dead:beef::ffff" }




But somehow it is not able to allocate more than 65515 ip's in that
subnet. Is there variable I can change to support more than that?
