The Shady World of IP Leasing
The IPv4 "exhaustion" is not real. The addresses got hoarded and the market devolved into a wild sub-leasing economy where anyone can choose where their IPs appear from, who owns them on paper, and scrub them clean of any history.
IPv4 "Exhaustion" is a Myth
You've heard it a thousand times: we've run out of IPv4 addresses. ARIN, RIPE, APNIC — every Regional Internet Registry (RIR) will tell you their free pool is depleted. And technically, that's true. The RIRs have no more fresh allocations to hand out. But the addresses didn't disappear. They got hoarded.
What actually happened is that IPv4 space became digital real estate. Companies, speculators, and holding entities scooped up massive blocks — some dating back to the earliest days of the internet when /8 allocations were handed out like candy — and now they sit on them, sub-leasing ranges to anyone willing to pay. The "exhaustion" isn't a technical crisis. It's a landlord problem. The addresses exist. They're just behind a paywall now, controlled by middlemen who've turned a public resource into a rental market.
What is IP Leasing?
Normally, if you need IP address space, you go to a Regional Internet Registry. There's a process. You justify your need, you provide documentation, your organization is tied to the allocation through WHOIS records, and there are policies governing how those addresses are used. The RIR system was built around accountability — every block is traceable to a responsible party.
IP leasing is the alternative that skips all of that.
IP leasing companies bypass all of that. You don't need to justify anything. You don't need to be a network operator. You pay, you get addresses, and depending on the provider, you can white-label them so your name never appears in any public record. Some of these companies will even register an ASN on your behalf under any RIR you want — you can be sitting in the United States and walk away with a RIPE (EU RIR) ASN that is geolocated to Africa. There's nothing stopping you. You get a fully functional routing identity without ever having to interact with an RIR directly or prove you operate a legitimate network. The accountability chain that the RIR system was built on — the entire reason we have WHOIS, IRR databases, and routing policy — gets severed the moment these addresses enter the leasing market. What you're left with is anonymous, untraceable address space that can be geolocated anywhere, cleaned of any spam history, and rotated on demand, announced by an ASN that exists on paper but answers to nobody.
And the services built on top of this leasing infrastructure should raise serious red flags. We're talking about paying to get IPs delisted from spam blacklists, choosing arbitrary geolocations with no validation, buying "unattributable" white-labeled address space, and renting residential IPs that make traffic look like it's coming from someone's house. These aren't niche services. They are the backbone of how major VPN and proxy providers operate, and they are actively undermining the trust infrastructure the internet depends on.
