We successfully deprecated site-local unicast addressing by painting it with
the stink of IPv4 network address translation. However, we retained the
technical consensus that unreachable nodes still need to be uniquely
addressable, and what's more: these unreachable global scope unicast
addresses must be assigned from a registry with a single global root.
My heretical opinion is that the second technical consensus is wrong. We
should deprecate the 'L' bit in the ULA address type and make all ULA into
locally allocated addresses. That way, we will have carved off a well-known
prefix (like all the other non-routable prefixes) where nodes are neither
uniquely addressable nor reachable on the public Internet. I contend the 'L'
bit was never a good idea; it was a placeholder for those wishing to retain
network address translation in IPv6. There, I said it.
agree... let's go back to the original RFC defining ULA and remove that
bit and using this entire thread over the last few months as a reason why
it never should be global unique etc....
