What a friendly, helpful place the modern Internet is! Like the forrest floor, its an ecosystem where things don't go to waste.
If you happen to inadvertantly leave your shiny /18 IPv4 block lying around, don't worry. It won't be long before some helpful Bulgarian, Romania, Ukranian or Russian will happen by, notice that you failed to route it, and then fix that for you, at no charge, and without you even having to ask. Then, as a bonus, also at no charge, he'll fill it to the brim with snowshoe spammers for you! How helpful! 124.157.0.0/18 (VietNam) -> AS44814 (Bulgaria)
