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?
You can fit the largest possible routing table in a PC with $500 worth of RAM.
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.
You can't? I know at least a few ISPs are running PC's with Zebra for their routing. I've seen ATM, Hssi and similar cards that appears to be supported. Where do things break down?
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?
I think me means it too large. Links these days are almost cheap enough (even in NZ) that very small companies may want to multihome. A Web hosting company could easily only need a /26 worth of IPs.
Perhaps we should forgo routers and just use switches in a flat address space?
I've seen that seriously suggested. -- Simon Lyall. | Newsmaster | Work: simon.lyall(a)ihug.co.nz Senior Network/System Admin | Postmaster | Home: simon(a)darkmere.gen.nz ihug, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
