Sitting on a /24 — or a /16 — you no longer route? Tell us the block and we value it on the spot. We verify ownership against the RIR registry, quote you a price, and run the full ARIN/RIPE transfer with funds held in escrow until it's done. You keep the upside; we handle the paperwork.
Enter the CIDR you want to sell. We'll validate it against the registry and route a priced offer to our desk.
Find out what unused IPv4 your organization holds — and what it's worth. We cross-reference the public RIR registry against the global routing table to surface the blocks registered to you that aren't announced on the internet, grade each one A–E, and estimate its market value. No cost, no obligation, no public listing.
Built on public ARIN/RIPE/APNIC/LACNIC/AFRINIC delegated stats and the public BGP table. OSINT only — nothing scanned, nothing intrusive.
Tell us your organization — that's all we need to get started.

Selling, step by step
From "I have a spare block" to money in your account — usually inside a couple of weeks.
Drop your CIDR in the form. We instantly check it against the RIR registry to confirm it's real and routable.
Our desk values it against live market rates and reputation, then sends a firm, no-obligation number.
Accept the offer, sign a simple purchase agreement, and the funds go into licensed escrow before anything moves.
We file the RIR transfer, see it through approval, and escrow releases your payment the moment it completes.
The bigger picture
The free pools ran dry years ago. Every regional registry has exhausted its general allocation, yet the internet still runs overwhelmingly on IPv4. That mismatch turned address space into a genuine asset class — one that has trended upward for a decade.
If your organization holds legacy ranges it no longer announces, that's idle capital. And if you're growing, buying or leasing clean space is often faster and cheaper than re-architecting around scarcity. We sit in the middle of both sides and keep the transaction clean, private, and registry-correct.

Your block is never publicly listed. Inquiries stay confidential from first contact to closing.
Registry-backed pricing in minutes, not a vague "we'll get back to you." You'll know where you stand quickly.
We screen blocks against major blocklists so clean space keeps its value — check yours below, free.
