But theoretically every filtered /24 could be routed via smaller prefix /23 /22 /21 or etc. I don't think this is true, even in theory, specially for legacy prefixes. There is probably somewhere a Geoff Huston survey on /24 without a covering route.
There's lots of legacy blocks out there that are only /24 in size... Like my primary IPv4 block, for example. I believe you'll also find them referred to as 'portable' blocks. -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
