We do not necessarily need such "a way to do lookups" that scales. Indeed for some architectures for how these identifiers might be used, we would need such a mechanism. But other architectures might have other ways of doing things (like referals might carry something other than just one of these flat identifiers). I think it might be helpful to understand all the different ways referals might be passed, and then in each case, what lookupability properties the various names, and locators would need to have. -Tim Shepard [EMAIL PROTECTED] -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
