We have already, all we're discussing now is if we do a better job of implementing it. Classful suffered from lack of space in each range and too coarse a set of fixed ranges, all fixable in v6 so perhaps it's not so bad? > So, if I need to break up my /32 into 4 /34s to cover different geographical > regions, I should instead renumber into a new range set aside for /34s > and give back the /32? And what if you need a few /48's, then you're open to others advertising some of yours too. With no organised mechanism of communicating acceptable prefix lengths to all routers [1] then we either do nothing and let anarchy rule, do something that overly constrains or do half the job and have both problems. > Perhaps we should give everyone an allocation out of each filter > range, so that they can simply number from the appropriately-classed > range; when you apply for space, you'd get a /32, a /33, a /34, a /35, > a /36, etc. all from the appropriate, statically defined ranges. > > *removes tongue from cheek* What would be most efficient for all? Semi classful or not I don't mind but it does seem pointless to have been going round the same circle for so many years. brandon [1] sbgp would be secure anarchy
