Buy IPv4 addresses safely

Businesses can buy IPv4 addresses when they need long-term control of public address space and want the resource transferred through the relevant Regional Internet Registry. Purchasing is suited to infrastructure that will remain in operation for years and where recurring lease payments are less attractive than ownership.

Buying IPv4 addresses is the permanent acquisition of an IPv4 block through an approved RIR transfer process. It gives the buyer long-term control of the resource, allows the range to become part of owned network infrastructure, and creates the option to route, retain, or monetize the address space after the transfer is complete.

IPv4 purchase prices and block sizes

Prefix	IPs	Price	Action
/24	256	From €25/IPone-time	Get a quote
/23	512	From €25/IPone-time	Get a quote
/22	1,024	From €23/IPone-time	Get a quote
/21 and larger	2,048+	From €20/IPone-time	Get a quote

Blocks may be sourced from the RIPE NCC, ARIN, APNIC, LACNIC, and AFRINIC service regions. The actual transfer path must be verified for the specific source and recipient RIRs; not every inter-RIR pair follows the same policy or is available in both directions.

The exact purchase amount depends on the selected prefix, RIR region, block history, market supply, and transaction conditions.

If ownership is not required, leasing IPv4 addresses reduces the upfront commitment. An owned block can later be monetized through leasing if part of the capacity becomes temporarily unused.

What should be checked before buying IPv4?

A purchase should include administrative and technical due diligence before funds are committed.

Important checks include:

seller identity and authority to transfer the resource;
RIR registration and transfer eligibility;
WHOIS and RDAP records;
route history;
reserved or bogon status;
reputation and blocklist records;
transaction and authorization documents.

The selected prefix should also reflect expected capacity. A /24 contains 256 addresses, a /22 contains 1,024, and a /21 contains 2,048.

What is an LOA?

A Letter of Authorization (LOA) is a signed document that authorizes the RIR to process the transfer of the IPv4 block from seller to buyer. We (as broker) help coordinate the LOA as part of the process.

How does an IPv4 purchase proceed?

Use case 01

Select a suitable block

The acquisition begins with the required prefix size, RIR, intended use, and technical conditions.

Use case 02

Verify ownership and eligibility

Confirm that the seller controls the block and that the resource is eligible for transfer.

Use case 03

Agree on commercial terms

Settle the price, payment structure, and transaction conditions before documents are prepared.

Use case 04

Prepare the documents

Prepare the purchase and authorization documents so the transfer package is complete.

Use case 05

Submit the RIR transfer

Submit the transfer to the relevant RIR for review and approval.

Use case 06

Complete registration

The block is registered to the buyer or its LIR once the transfer is completed.

After transfer, the block can be announced through the buyer's network providers, retained for future capacity, or used for supported BYOIP deployments.

When is buying more practical than leasing?

Buying is suitable when the range is expected to remain part of the infrastructure for the long term. Ownership removes lease-renewal risk and gives the business more control over future use of the resource.

Leasing can be more appropriate when demand may change, the project has a limited lifecycle, or the organization prefers recurring operating expenditure over a larger initial investment.

Buy vs lease

Feature	Buy	Lease
Ownership	Full — RIR transfer to you	No — holder retains
Upfront spend	High one-time payment	Usually none
Typical term	Permanent	1 month – 3+ years
Recurring cost	None after purchase	Monthly or quarterly
Flexibility	Low — you own it	Moderate — renew or return
Best for	Long-term infrastructure	Dedicated use without buying

Common buy use cases

Use case 01

Cloud and hosting

BYOIP, customer allocation, or steady capacity where you want the addresses under your own control.

Use case 02

Enterprise infrastructure

A fit for internal networks, data centers, and projects that are not going away in six months.

Use case 03

VPN and proxy

Useful when block history, routing control, and keeping the same space long term all matter.

Use case 04

Investment or lease-out

Some buyers want operational use today and the option to lease out or resell later.

Frequently asked questions

What is the smallest IPv4 block commonly purchased?

A /24 containing 256 addresses is the usual starting point and the practical minimum for reliable global BGP announcement.

Do I need an LIR to buy IPv4?

The receiving structure depends on the RIR. In many transactions, an LIR or regional equivalent is used to receive and register the transferred resource.

Is the indicative price the final transaction amount?

Not necessarily. The final amount depends on the block, RIR, market conditions, and transaction structure.

What can be done with the block after transfer?

It can be routed for internal infrastructure, retained for future expansion, or leased out when part of the capacity is not required.
