Since the ipv4 situation has worsened ARIN is allowing and encouraging owners of ip space to lease their unused space.. I've run across some brokers but I get the feeling I need a strong legitimate sounding story before contacting them. I've never owned or leased IP space so I may be a bit naive on what kind of information they're looking for. Apparently people are getting burned by email spammers, so they're looking to make sure you're legit. I notice geo-location databases will classify "network speed" on a network.. Most private proxy providers seem to get theirs to show up as DSL or Cable. Do you just have to look for subnets that already show up this way or is it something you can set? It looks like the minimum is usually a /21, which would be pretty easy to justify I think by saying its for a VPS hosting company? I'd appreciate any wisdom as I'm hoping this is a possibility.
