I was trying to configure native ipv6 on my NixOS box, which is running in online.net's datacenters. They provide you a /48 or smaller subnet and a DUID which is used during DHCP. In dhcpcd vocabulary DUID is called clientid.

online.net's help page about IPv6 configuration was not very useful, since NixOS uses dhcpcd by default. The page which allowed me to make it all work was https://community.online.net/t/tutorial-ipv6-with-dhcpcd/3804

It looks like the only really required entries in networking.dhcpcd.extraConfig are interface and static though. I assumed that clientid is also necessary, but it looks like dhcpcd cares much more about content of /etc/dhcpcd.duid. Of course replace enp2s0 with the name of the main interface.
