It makes me wonder just how much space like that there is out there artifically increasing IP scarcity.
The fact that there is a lot of space assigned/allocated and not used in any easily observable way is well known to those who track the address exhaustion issue, I think.
How much, though, is used, but not routed publically? Something that has been brought up from time to time here. It's not easily observable, but allowed. scott

----------------------- TOTAL FOR IPV4 BLOCKS: Allocated: 9302367 (/24 blocks) - 63% Not Allocated: 5377697 (/24 blocks) - 37% Currently Routed: 6183529 (/24 blocks) - 42% Not Routed: 8496535 (/24 blocks) - 58% ----------------------- Simple math from above: Allocated & Not Routed: 3118838 (/24 blocks) - 21% This is from my data available at www.completewhois.com/statistics/ (which is for some reason partially broken right now - has all the correct data but coloring of bars did not happen). The percent calculation does not include class-d and class-e (i.e. only blocks 0/8 - 223/8 are counted).

Not easily observable means some ip blocks maybe used but are not adverised in public BGP. This is a bit of an issue with certain part of US Gov.

The larged of these blocks are 6/8, 11/8, 21/8, 22/8, 25/8, 26/8, 28/8, 29/8, 30/8. 51/8, 52/8, 56/8 and I strongly suspect 48/8. This comes to total 851968 /24s; this still leaves 2266870 /24 blocks that includes some smaller used but not advertised and some no-longer-used space. I suspect the total would be around 1/2 of value above, i.e. around 10% of ip space is something that could potentially be reclaimed (that is unless you want to bug us military who have way too much space). -- William Leibzon Elan Networks william@elan.net
