I see it different than Lee ... because, there are no new ipv4 addresses they are all used. I have seen the same spam issue with IP space that is sold. So be careful. I have been involved in both leasing and purchasing IPv4 space. Like everything else you want to check the mileage/usage and look for dents before leasing or buying. No matter which method - verify you are getting clean addresses before spending a dime. Purchasing can be a large upfront investment - leasing is a good option for many. We all know someday the space won't be needed. It's just a matter of when. My advise if you have cash and time buy IPv4 space. If not lease and focus on spending the cash on newer gear that can handle all the /24s and IPv6 prefixes. If leasing, make sure you are dealing with a source that watches carefully and can provide you multi-year contract optioned space....so you can toss them away when IPv6 is it. Thank You Bob Evans CTO
Leasing is ill-advised; the addresses will be unsellable once the spammers are through with them. Really, there¹s no other reason to lease.
If you want to buy or sell addresses in the ARIN region, some of the facilitators at https://www.arin.net/resources/transfer_listing/facilitator_list.html are pretty good (ask me; I¹ll let you know my opinions privately).
The only ones I know who will deal in blocks as small as /24 are http://www.ipv4auctions.com/ There may be others I don¹t know about.
Of course you have to ask whether IPv6 is a possible alternative, and you shouldn¹t go to all the troule and expense of buying addresses without turning up dual-stack. That would be like spending $20 for a tissue when you need a $10 cold medicine; it helps, but not for long.

We have customers asking to lease IP space for BGP transit with us and other peers. But they are struggling to get at a minimum even a Class C, even though they have their own ASN. We don't have large amounts of free IPv4 space to lease out to a single customer in most cases anymore. Hope to at least introduce these customers to some contacts that may be able to help. Do we know of any reputable sources that are leasing or selling IPv4 subnets as small as a /24 to satisfy their diversity needs? Thanks!
