Actually, I don't think your situation is one of those circumstances envisaged.
In the IPv4 world, once a client is configured (which requires broadcast packets), then it may unicast packets (eg to renew a lease) to the server - it knows the server address because it's part of the information supplied to it. I'm not familiar enough with IPv6 to say if this is (effectively) the same.
