Как DHCP v6 настроить на сервере Ubuntu 18.04 , чтобы он выделял локальные адреса?

Я пытаюсь настроить DHCP v6 версию на сервере. Получаю кажется ошибку множественности сетей на одном интерфейсе. Хотя в IPV6 это можно и очень много. В текущем состоянии адреса получаю с удалённого DHCP сервера, а нужно чтобы локальный сервер выделял внутренние адреса fd00:a000::/64 Как вообще DHCP v6 настроить на сервере Ubuntu 18.04 , чтобы он выделял локальные адреса?

В рабочем состоянии пишет такое

$ systemctl status isc-dhcp-server6.service

Попытка добавить подсеть fd00:a000 DHCP серверу приводит к ошибке , и просто запись для выделения адресов 2a03:xxxx:xxxx:6666:ffff::/80 вообще не работает.

/etc/dhcp/dhcpd6.conf

subnet6 2a03:xxxx:xxxx:6666::/64 {
    range6 2a03:xxxx:xxxx:6666:fffe::1 2a03:xxxx:xxxx:6666:fffe::fffe;
    range6 2a03:xxxx:xxxx:6666:ffff::/80 temporary;
}

subnet6 fd00:a000::/64 {
#       range6 fd00:a000:0:0:ffff::/80 ;
#       range6 fd00:a000:0:0:fffe::/80 temporary;
}
