Good evening,
we are a small hosting / network provider in Switzerland and are running
our infrastructure "IPv6 first" - aka only adding IPv4 where necessary
and the core network is 100% IPv6 only.
All of our hosting customers currently have 1 IPv6 address
assigned and can request a /64 network, which we currently manually
route to their VM.
We are now considering an infrastructure revamp and would like to switch
to more "standard techniques", like DHCP & DHCP PD.
When looking at the ISC DHCPd, we see that there is PD support, however
some things are rather unclear to us:
- Given that you can trust the mac address (we can ensure that), how do
you ensure that a client can only request a certain number (1, 2, x?)
prefixes?
- Similar: is there a way to grant clients access to a /64 or /48 (or
anything in between) defaulting to /64?
- How does dhcpd ensure that a system is adding the respective route to
the client? If it is not dhcpcd, how is it commonly solved?
- Does dhcpd have hooks? If yes, what kind of hooks are available and
how do we pass information to them?
I hope we have not overseen the documentation parts for these questions,
but if so, we would be happy if you point us to it.
Best regards from the mountains,
Nico

It should be able to do all you want and you will be more flexible.
