I believe that a substantial amount of the remaining IPv4 space should be put aside to be used with whichever new architecture is developed to deal with the routing and addressing problems discussed last year in the IAB RAWS workshop.
sure. in a lead-lined concrete vault for our grandchildren. the routing architecture issues the usual suspects are churning have been the same for decades, yes plural. i find the least optimism that they will be resolved by these same folk in my lifetime amusing at best. until the map and encap and other hackers give way to good math folk, we will get nowhere. and there has been zero motion in this direction. randy -- see B. Fortz and M. Thorup. Internet traffic engineering by optimizing OSPF weights. In IEEE INFOCOM, March 2000 for what happens when serious math folk get interested for a few months.
