Thanks for the pointer. > Anyway, we may be able to learn something from the > experience (not to waste time, not necessarily to reject the idea > again). I'm sorry, but I don't have time to dig the minutes or ML > archives on the discussion for now. It's definitely worthwhile to learn from the past. The draft is available at: http://www.join.uni-muenster.de/drafts/draft-francis-ipngwg-unique-site-local-00.txt The meeting was March 2001. Text from minutes http://playground.sun.com/ipv6/minutes/ipng-minutes-mar2001.txt : ==== IPv6 Near-Unique Site-Local Addresses / Paul Francis <draft-francis-ipngwg-unique-site-local-00.txt> ---------------------------------------------------- [See slides at http://playground.sun.com/pub/ipng/html/meetings.html] Proposing to make site local prefixes non-local by adding a random number to "zeros part" in site local addresses. Now thinks that this doesn't help with the main problems stated in the draft. When merging sites, half will still have to renumber. Not any different from using the current site local prefix. In both cases some of the subnets will have to be renumbered. Crawford: Not quite as bad. When merging each half could maintain their original unique prefixes. Deering noted that notion of sites is not whole companies. More like a notion of a campus. He also thinks we should think about non-routable global address space. Thinks there may need for that. Something like a special TLA that ISP's will never route in the global Internet. Alain Durand, think this is unnecessary as we have lots of global addresses and we don't need to create way to use local addresses for non-local communication. Additional discussion. ===== But, when merging two sites, you don't need to renumber unless you want to. -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems.
