IPv6 management in network?

My ISP does not provide me a prefix; it goes straight to /128 so I am forced to implement local IPv6 networking, which is a pain in the butt...

Do you know of tools or helpful docs to construct ULAs and alike to configure DHCPv6? I only have two (V)LANs (Clients, Servers) so it should not be that complicated I'd assume.

IPv6 is one of the network topics that just completely breaks me and I could never have that "a-ha!" moment where it just clicks... iunno, likely a Layer-8 problem but a problem nonetheless. x)

Thanks! =)
