Yes of course names should be used in configurations whenever possible, but the hosts and network elements tend to use addresses under the covers. >>> The point is, if you're updating the DNS entiries anyway, why would you >>> care about the special magic (i.e., tokenized IIDS)? -- the meat seems >>> to the in the renumbering case. >> Site managers of enterprise networks like predictability, and >> they don't want things to change in the case of a swap of the >> physical server, and of course they don't want to manually >> configure an IPv6 address on the new box. > > They will have to configure the tokenized IIDs, anyway. - again, I think > the meat is in the renumbering case. It's because all networks need to be renumbered some day that it matters, yes. >>> I'd set the DNS aside -- at least this I-D doesn't mention any mechanism >>> to notify the DNS of the updated *prefix* (and you probably wouldn't >>> want that, anyway). >> It's a separate problem, but yes, I would want it automated (and >> secure, of course). > > So far there's no support for that in the DNS, is it?
