<p class="MsoNormal"><span style="color:windowtext;mso-fareast-language:EN-US">In a sense all host addresses are /128 entries. The important thing is that the routing table includes a route for the /64 block containing the address. As long as that is there
your system should work properly. That should be learnt from the RA rather than DHCP.<o:p></o:p></span></p>

<p class="MsoNormal">Hi<br>
<br>
Thanks for the feedback, my router is pfsense firewall and I haveconfigured the LAN side Router Advertisements as
<br>
Managed -RA Flags [managed. other stateful], Prefix flags [onlink, router] but the dhcp6 client get a ::/128 address<br>
I have also configured the correct RA subnet for the interface but while the clients get an IPv6 address from the pool, the subnet is still wrong.<br>
<br>
Thanks<br>

<b>Ämne:</b> [Kea-users] Kea 1.6 DHCP6 configuration on Raspberry Pi 3b running Ubuntu 20.04

<p class="MsoNormal">Hi,<br>
<br>
I have successfully configured HA between two Raspberry Pi 3bs running <br>
Ubuntu server 20.04 with repository Kea 1.6 version.<br>
<br>
I have configured a DHCP6 range and a pool but the client always has a <br>
::/128 address.<br>
<br>
As I have a mixture of staticly assigned and dhcp6 clients in the same <br>
::/64 subnet, I have specified my ::/64 subnet in the<br>
<br>
{<br>
"id": 2012,<br>
"pools": [ { "pool": "NNNN:PPPP:QQQQ:T:ffff::/80" } ],<br>
"subnet": "NNNN:PPPP:QQQQ:T::/64",<br>
"interface": "eth0",<br>
"option-data" : [<br>
{<br>
"name": "domain-search",<br>
"csv-format": true,<br>
"data": "euclid.plato"<br>
},<br>
{<br>
"name": "dns-servers",<br>
"data": "NNNN:PPPP:QQQQ:T:8213:1132:6645:2222"<br>
},<br>
{<br>
"name": "sntp-servers",<br>
"data": "NNNN:PPPP:QQQQ:T:8213:1132:6645:2222"<br>
}<br>
<br>
]<br>
<br>
}<br>
<br>
How I can I assign a ::/64 address which is selected from only a smaller <br>
portion of the ::/64 subnet so that the client is assigned a ::/64 address.<br>
<br>
Thanks<br>
<br>
Russell<br>
