[Kea-users] Kea 1.6 DHCP6 configuration on Raspberry Pi 3b running Ubuntu 20.04

[russell aspinwall]

Hi,

I have successfully configured HA between two Raspberry Pi 3bs running 
Ubuntu server 20.04 with repository Kea 1.6 version.

I have configured a DHCP6 range and a pool but the client always has a 
::/128 address.

As I have a mixture of staticly assigned  and dhcp6 clients in the same 
::/64 subnet, I have specified my ::/64 subnet in the

{
           "id": 2012,
           "pools": [ { "pool": "NNNN:PPPP:QQQQ:T:ffff::/80" } ],
           "subnet": "NNNN:PPPP:QQQQ:T::/64",
           "interface": "eth0",
          "option-data" : [
              {
                 "name": "domain-search",
                 "csv-format": true,
                 "data": "euclid.plato"
              },
              {
                 "name": "dns-servers",
                 "data": "NNNN:PPPP:QQQQ:T:8213:1132:6645:2222"
              },
              {
                 "name": "sntp-servers",
                 "data": "NNNN:PPPP:QQQQ:T:8213:1132:6645:2222"
              }

       ]

}

How I can I assign a ::/64 address which is selected from only a smaller 
portion of the ::/64 subnet so that the client is assigned a ::/64 address.

Thanks

Russell
