They might, and the addresses might have a one-to-one relation too. For example, this kind of scheme will appeal administrators: 2001:xxxx:yyyy:1234:IID FEC0:0000:0000:1234:IID > I'm just trying to understand if SLs really do have > utility in a renumbering protocol. In theory, yes. In practice, I doubt it though. As Bob mentioned, configuring SLs is a manual operation; unless there are some new developments that I am not aware of, I don't see how this could realistically be automated. IMHO, the relation between SLs and renumbering is this: SLs are used in parts of the network that have no access to the public Internet in order to avoid the renumbering of that part in case of an ISP change on the part that does have access to the outside. This is especially important on networks when 95% of the network does *not* have access to the Internet.
