I took Steve up on his suggestion of looking through the archives on this
topic.
With some effort I found three threads, all initiated by Christian, in May
'97, Dec '97, and Nov '99. I saved the relevent messages...you can find
them at http://www.aciri.org/francis/IPv6_site_id_threads.txt if you are so
inclined. This is probably not exhaustive, so if anyone can point me to
other threads that would be helpful.
I didn't see any major ideas in the previous threads that weren't in the
latest thread.
A problem I found when looking over the threads is that a complete picture
of what a site ID would be and how it would work was never generated, with
the end result that different people were talking about different things and
to some extent talking past each other.
Having read the arguments, I still believe that there is something to be
said for the site-ID notion. The site-ID would be for sites that want to
have their own number space for internal communications, with reasonable
assurance that nobody else is using the same space.
The site-ID would not supplant the use of site-locals by other sites who
wanted to use them. Site-locals would remain as defined.
A site-ID would also not by itself identify what is and is not in a given
"site". In other words, one couldn't take two addresses with site-IDs and,
in the absense of any other information (DNS entries or routing tables) say
definitively whether they could or could not reach each other using the
site-ID addresses.
I'm inclined to write a draft specifying this so that we can have a focused
and consistent (and dare I say difinitive?) discussion about it. Is there
anyone out there who in principle likes the idea of site-IDs and would care
to work with me on this?
Thanks,
PF
