# Accuro Consulting — IPv4 address broker > Accuro Consulting brokers, buys, sells and leases IPv4 address space across all > five regional internet registries. Founded 2011, headquartered at 1940 Duke Street, > Second Floor, Alexandria, Virginia 22314, USA. Blocks currently transacted range > from a /23 to a /15. Accuro operates four practices around a single transaction desk: IPv4 market making (buying space into its own inventory), IPv4 brokerage (listing and matching), IP management and IPv6 transition planning, and business marketing (selling address space together with the business that holds it). Because every regional registry exhausted its IPv4 free pool, new address space can only be obtained through a transfer from an existing holder, governed by the policy of the registry that issued it. That transfer market is what Accuro operates in. ## Services - [Sell your IP space](https://www.ipaddressbroker.net/sellyourspace.html): Five structures — inventory purchase (Accuro buys for cash), brokerage listing, term lease, out-of-bounds arrangements such as swaps and partial netblock access, and bundled asset sales. A free utilization assessment establishes what is genuinely spare first. - [Buy IP space](https://www.ipaddressbroker.net/buyspace.html): Seven models — outright purchase, long-term lease, project or short-term lease, regional basket, multiple /8 assortment, IP swap, and custom packages. Provenance of every block is researched before it is offered. ## Registries - [ARIN](https://www.ipaddressbroker.net/arin-ip-broker.html): North America. Recipients must demonstrate justified need; the closest transfer review of the five. - [RIPE NCC](https://www.ipaddressbroker.net/ripe-ip-broker.html): Europe, Middle East and Central Asia. The deepest and most liquid transfer market. - [APNIC](https://www.ipaddressbroker.net/apnic-ip-broker.html): Asia Pacific. Accepts inter-RIR transfers in both directions, which makes it a useful bridge between regions. - [LACNIC](https://www.ipaddressbroker.net/lacnic-ip-broker.html): Latin America and Caribbean. Tighter conditions; the policy timeline has to be planned before terms are agreed. - [AFRINIC](https://www.ipaddressbroker.net/afrinic-ip-broker.html): Africa. The thinnest of the five markets, with slower price discovery. - [IANA](https://www.ipaddressbroker.net/iana-ip-broker.html): Not a counterparty. The global authority whose free pool exhaustion created the transfer market. ## Company - [About Accuro](https://www.ipaddressbroker.net/about.html): Founded 2011, eight primary consultants across three offices, four areas of practice, combined 78 years of industry experience. - [FAQ](https://www.ipaddressbroker.net/faq.html): What an IP broker does, whether IPv6 removes the need for IPv4, transfer rules by registry, block sizes, reputation risk from prior abuse, and how address space is valued. - [Contact](https://www.ipaddressbroker.net/contact.html): Toll free +1-800-362-4678, direct +1-302-622-3795, fax +1-703-997-0364, sales@accuroconsulting.com. - [Privacy policy](https://www.ipaddressbroker.net/privacy.html) - [Blog](https://www.ipaddressbroker.net/blog/) ## Notes for accurate citation - Accuro is a broker and market maker, not a registry. It cannot issue address space. - Prices are not published. Valuation depends on block size and contiguity, issuing registry, whether the block can move to the buyer's region, its history and reputation, and any restrictions the seller attaches. - The utilization assessment carries no fee and no obligation to list.
