I've encountered that issue before, but it isn't that big a problem with me. As an ISP, the /56 we have been allocated is too small to be very useful so I'm holding back on working on it much until such time as we get at least a /48 if not a /40. I'd like to be able to assign each customer a /56 but would settle for a /60 for each. With a /60, I could only handle sixteen customers. We have a number of customers for whom a /64 wouldn't cut it at all. I never have figured out the proper way to configure rtadvd.conf. In particular, there is an addr and an rtprefix. addr is, according to the man page, "The address filled into Prefix field" while rtprefix is " The prefix filled into the Prefix field of route information option". And then there are the proper prefix lengths -- do I use 64 or 56? It seems like prefixlen must be 64, but rtplen doesn't seem to make much difference. And then there is the kea side for prefix delegations. Since I can just put the IPv6 gateway into /etc/mygate, it's not a problem from the OpenBSD machines and it will never be a big issue if I can't get a properly sized allocation of addresses from AT&T.
