Many routers still are like this... There are only 14 million or so possible /24 blocks. Even if every possible /24 was advertised (and they aren't), the routing table and all its related hangers on should fit inside a gig or so. Whas that got to do with the real world? I can buy a PC with enough horsepower and memory to run the routing for the worst cases we're likely to see on the Internet for around NZ$3000. Irrelvant, and besides, no you can't. Really, this "gotta have a small prefix" thing is silly. it prevents outfits that have small address space needs from peering with multiple providers without massively wasting address space. What do you mean here? That a /24 is too large for many people or that filtering on assignment boundaries is bad? Sure, if you're singly connected, you don't need provider independant address space. But applying thinking based on 1980s routing technology to address space management is just dumb. Technology is only part of the problem, this is also the issue of sane management and keeping networkds usable. Perhaps we should forgo routers and just use switches in a flat address space? --cw - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
