Brokerage
Our main practice. Your block is listed to the widest buyer network we can reach and sold only on the criteria you write into the offering memo — including what the space may be used for once it leaves you.
How a listing works →IPv4 brokerage · market making · since 2011
Somebody already owns the addresses you need.
Every regional registry’s free pool is empty. Growth now means a transfer: a vetted block, a compliant filing, and a counterparty who is exactly who they say they are. That is the whole job, and it is the only job we do.

What does an IP address broker actually do?
An IPv4 broker connects an organisation holding address space it no longer needs with one that needs space it cannot get from a registry. The broker values the block, finds and vets the counterparty, structures the deal — sale, lease or swap — and files the transfer with the registry that governs it. Accuro has done this since 2011, and also buys space into its own inventory when a seller needs cash faster than a listing can deliver it.
What we do
Four practices around one transaction desk.
Eight consultants and their support teams, across market making, brokerage, IP management and business marketing. Most clients arrive through one practice and end up using two.
Market making
We hold inventory, so we can be the buyer instead of the middleman. When timing matters more than the last percent of price, you get a firm offer rather than a listing period.
Request an offer →IP management & IPv6 planning
A utilization audit, an efficiency analysis, a consolidation report and a one, three and five year growth model. No fee, and finished before you commit to anything.
Book an assessment →Business marketing
When the address space is worth as much as the company, both are sold together: appraisal, third-party valuation, feasibility study, one closing and one set of documents.

Selling is a liquidity decision. Buying is a schedule decision.
Nobody arrives with the same constraint. Some need capital this quarter; some need three hundred addresses for a migration that ends in March. Choose the structure first — the price follows from it.
If you hold space
inventory
Inventory purchase. Capital now, at a price we quote and stand behind. No listing period, no waiting for a counterparty.
brokerage
Brokerage listing. Your space listed to the largest buyer network we can reach, sold only to a buyer who meets the criteria you set.
lease
Term lease. A defined term for space you expect to need again. Useful when a consolidation frees addresses you have earmarked for a later project.
out-of-bounds
Out of bounds. IP swaps, region swaps, partial netblock access, and the arrangements that do not fit a standard template.
bundle
Bundled assets. When the addresses are worth as much as the business, both are sold in a single transaction with one closing.
If you need space
purchase
Outright purchase. You take a lifetime license to the space and deploy it however your network requires.
lease-long
Long-term lease. A use license for a defined period beyond one year, with no capital outlay against a dual-stack timeline.
lease-project
Project lease. Sized to a migration, a consolidation or a launch, drawing on inventory for short periods.
basket
Regional basket. An assortment drawn from different RIRs, for buyers who need presence in more than one region.
multi-8
Multiple /8 assortment. Groups of smaller netblocks assembled from separate /8s where reputation isolation matters.
swap
IP swap. Exchange space with another holder to shift exposure across regions or netblocks without a cash purchase.
custom
Custom package. Where none of the above fits, the structure is built around the constraint you actually have.
Regional coverage
Five registries, five rulebooks, one filing team.
ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC each govern who may transfer what, to whom, and on what justification. Our regulatory team sits inside every transaction so the filing clears the first time.
Why it matters now
IPv4 space is a perishable asset that most balance sheets ignore.
The world stopped issuing new IPv4 addresses in 2011. IPv6 deployment has grown steadily since, but almost every network that reaches the public internet still needs IPv4 to be reachable by everyone — which is why dual-stack, not IPv6-only, remains the practical default. That gap is what gives idle IPv4 space its value, and why leaving it unused is a decision with a cost attached.
Selling is not the only answer. A block you expect to need again can be leased instead. A block that is only partly idle can be consolidated first, so you sell what is genuinely spare rather than what happens to be easy to identify. That analysis is where most of our engagements begin.
What we need from you to start
- The prefixes you hold and which registry issued them.
- Roughly how they are used — a utilization estimate is enough for a first conversation.
- Your constraint: a date, a capital need, or a limit on who may end up on the space.
From that we come back with a structure, a timeline and a number. Contact a consultant to begin, or read the frequently asked questions first.
