DHCPv6 clients that can request multiple prefixes (lemmy.world)

I'm on att for my home internet and unless you go to the effort to bypass their router (it does 802.1x authentication so it's a bit of a pain to do so), they only give you /64s via dhcpv6 prefix delegation, nothing bigger. You can request up to 8 of them though.

It looks like mikrotik can't request multiple prefixes in a single request, based on their documentation.

Edge routers look like they can if configured from the cli.

I've been using a linux box with dhcpcd and that works. Would be nicer if systemd-networkd supported multiple prefixes directly so I didn't have to try to get dhcpcd and systemd-networkd to try to play nice with each other since I use systemd-networkd for the lan side interfaces, wireguard, etc.

What other routers and dhcpv6 clients support requesting multiple prefixes in a single request? I'm looking to see if there's a better option out there than what I'm doing now.

I believe a fix for this was merged last year please read https://github.com/systemd/systemd/issues/22571 and https://github.com/systemd/systemd/pull/22574. Check what version it was actually released and if your Linux latest version already has it.

Another option would be to create a bridge and/or macvlan and them place multiple virtual connections on it, each one requesting and having a different IPv6 prefix.
