Hi John,

I think that when you're specifying the pool as a network ({ "pool": "aaaa:bbbb:cccc:dddd::/80" }), kea is assuming that the very first IPv6 is a "valid" one.

Try specifying the pool as a range of IPv6, or, at least configure an exception (not to serve) the address ...::0 of /80.

Regards,

Joelson

Hello,

running kea-dhpcv6 version 1.9.5.

Excerpt from my config:

"subnet6": [ { "subnet": "aaaa:bbbb:cccc:dddd::/64", "pools": [ { "pool": "aaaa:bbbb:cccc:dddd::/80" }  }]

Problem is that a client (Windows 7) gets aaaa:bbbb:cccc:dddd:: as its IP address. I activated debuglog with 99 verbosity and found no warning or error, it just hands out aaaa:bbbb:cccc:dddd::
Client gets DNS servers successfully.

Network uses DHCP relay. M and O flags are set.
In other networks/VLANs with same configuration but different DHCPv6 server it works without any problem.

Thanks for your advices.

John
