And in the event the owner can't be contacted? And if contact is successful, and the owner says "I'm just holding on to it because I like have 10 /24s" or, worse, he gets the clue and just starts advertising the space, without using it? Then we have both address space waste and routing table bloat...
While that is certainly problematic, it's just not worth dealing with until all of the truly unused space is reclaimed or voluntarily returned AND we have run out of new space to assign. Most people will Do The Right Thing when given the chance. Case in point: about 6 years ago, I emailed the contacts for every unrouted block within a particular swamp /16. The overwhelming majority offerred to give (not sell) the block to me, a few didn't respond, and a couple dozen indicated they were using or planning to use the block in the near future. I dropped the project, having more important things to do, but I figure I could have snatched up a sizeable portion of the swamp just by asking. Too bad ISI got into the game before I thought of it again ;) S Stephen Sprunk "God does not play dice." --Albert Einstein CCIE #3723 "God is an inveterate gambler, and He throws the K5SSS dice at every possible opportunity." --Stephen Hawking
