Frequently asked questions

An IP address broker connects an organisation holding IPv4 space it no longer needs with one that needs space it can no longer obtain from a registry. The broker values the block, finds and vets the counterparty, structures the transaction as a sale, lease or swap, drafts the agreements, and files the transfer with the registry that governs it. Accuro also makes a market, meaning it will buy space into its own inventory rather than only introduce a buyer.

Not soon enough to change your planning. IPv6 deployment has grown steadily, but a network that wants to be reachable by everyone on the public internet still needs IPv4, which is why dual-stack rather than IPv6-only remains the practical default. Planning an IPv6 transition and acquiring IPv4 for the interim are complementary decisions, not alternatives.

There are five structures: an inventory purchase for capital now, a brokered listing to maximise price, a term lease if you expect to need the space back, specialty arrangements such as swaps and partial netblock access, and a bundled sale where the addresses go with the business. The selling page sets out each one and when it is the right answer.

Yes, as do RIPE NCC, APNIC, LACNIC and AFRINIC — but each has its own rules on who may transfer what, to whom, and on what justification, and some also govern transfers between registries. Our regulatory team handles the filing as part of the transaction, so requirements are met before submission rather than discovered after a rejection.

Space currently moving through Accuro ranges from a /23, which is 512 addresses, up to a /15, which is 131,072. Smaller and larger blocks come up; if your holding or your requirement sits outside that range, ask rather than assume.

That risk is real: address space carries its reputation with it, and blocklist entries transfer along with the block. Every party to every transaction is researched and vetted, and the history of the space itself is examined in detail before it is offered. Accuro provides a guarantee and warranty to each party in every transaction.

You set the criteria. Your consultant determines the kind of user your space should go to and restricts marketing to that type of buyer, so you control who is allowed onto space that adjoins ranges you keep. Where the deal calls for it, we continue monitoring the space for the life of the transaction.

No. Short-term and on-demand leasing let you adjust the amount of space you hold at each renewal, and very short needs such as a migration or a network consolidation can be accommodated. See the project lease model.

Yes, and this is where most engagements start. The free assessment covers current utilization and internal distribution, an efficiency analysis of how allocated space is being used, a consolidation and optimization report, and a growth model over one, three and five years. You get a report identifying underused or unused blocks, and nothing is listed until you decide it should be.

In many cases, yes. Inter-RIR transfers are permitted between several of the registries, which is what allows a buyer in one region to acquire space held in another. Which pairs are open, and what each side requires, depends on current policy at both registries — that determination is part of structuring the deal.

By the things a buyer actually pays for: the size and contiguity of the block, which registry issued it, whether it can move to the buyer’s region, its history and current reputation, and the terms you attach to the sale. A restriction on permitted use protects you but narrows the buyer pool, and that trade-off is part of the conversation before anything is marketed.

Three things: the prefixes you hold and which registry issued them, a rough estimate of how they are used, and your actual constraint — a date, a capital need, or a limit on who may end up with the space. From that we come back with a structure, a timeline and a number.
