okay, give the job to someone else who can do it well then. vendors don't seem to have any trouble assigning a unique serial number to each products. this isn't rocket science. > > > If the site-ids are > > > globally unique, how are they any different from global addresses? > > > > they have a different prefix so they can easily be distingiushed > > from public addreses. > > But with a globally unique site-id, they are globally routable. no, they're *potentially* globally routable, but only if every network agrees to route them. which they won't because there will be too many of them. so no, they won't be globally routable in general. a few may be routable on limited portions of the public network because they've made special arrangements with particular ISPs, but that's between them and their ISPs. > If the site local addresses are used within a private > network, there is no need for a global registry since they won't be > seen in the global Internet. not so, because the private networks and the public internet are not disjoint. they overlap, and apps on hosts that appear in multiple networks have to deal with addresses from each of those networks. it's a bit like the problem of a host with multiple interfaces trying to send traffic to a link-local address. to which interface does it send the traffic (in the absence of explicit information)? can it use a LL address in a referral to peer on a different host? etc. you get the same problem with non-unique SLs that you do with LLs just at a different scale.
