We are last calling this document for the second time, for two reasons. The first reason is to make sure that the last call has been circulated widely enough in the community. The second reason is that we want to call the attention of the IETF community on the specific issue of using IPv6 addresses as identifiers in this manner. To summarize the background, the document suggests the allocation of a temporary experimental block out of the IPv6 address space for the purposes of easing experiments that deal with identity-locator split. In particular the HIP community wants this in order to be able to run unmodified applications. The allocated address space would be used to represent identifiers in the place of addresses in the existing APIs. While the long-term plan is to use new APIs that reflect the semantics appropriate for identifiers, the ability to experiment without having to upgrade all applications is important. Such an approach is not without problems, however. For instance, applications that deal with referrals (e.g. one application passing an address to another one) may end up "leaking" such identifiers to the hosts that are not involved in an experiment. Since the identifiers are not routable in the current Internet, communications initiated towards such identifiers will fail. My own take on this issue is that there are risks, but that the benefits are greater. In particular, its clear that the identity-locator split proposals need more experiments and experience before we can consider them for real. Making such experiments easy is important. Also, IMHO, the topic is sufficiently far in the domain of research that the practical danger of the experiment becoming a permanent problem is small. But this is enough about my opinions.
