I've seen that option but the documentation is not very clear. I
thought it was only to activate PD on the server part. I'm probably
wrong.

I've just tried to add
  IPv6PrefixDelegation=True
in my .network file. But it didn't change anything in the dhcpv6
requests sent by this server. Only inf-req packets, not solicitation,
and no prefix delegation in it.

Did I miss something ?

Thanks
