How to Lease IPv4 Address Blocks in 2026 (Step-by-Step Guide)

If you’re a hosting provider in the US or EU scaling infrastructure in 2026, you’ll likely need to lease IPv4 address blocks sooner or later. With the IPv4 free pool exhausted at all major RIRs, the secondary market and IPv4 leasing have become the practical path for most operators.

This guide walks you through how to lease IPv4 addresses step by step—whether you go through RIR processes or an IPv4 marketplace—so you can get the space you need with minimal friction and capital outlay.

Why Hosting Providers Lease IPv4 Instead of Buying

Leasing IPv4 address blocks offers several advantages over purchasing, especially in 2026:

Lower upfront cost — Purchase prices per IP can reach $35–60 or more. Leasing typically runs $0.30–0.50 per IP per month for standard tiers, preserving capital.
Faster deployment — No RIR transfer process. You receive a Letter of Authorization (LOA) and can announce your prefix within hours.
Flexibility — Scale up or down as client demand changes without committing to a permanent transfer.
No long-term lock-in — Ideal for pilots, seasonal workloads, or markets where demand is uncertain.

For hosting providers serving US and EU markets, IPv4 leasing has become a core strategy. Around 40% of IPv4 transactions now involve leasing rather than permanent acquisition—and that share is growing.

Step 1: Decide Your Block Size and Requirements

Before you start, define what you need:

Block Size	Addresses	Typical Use
/24	256	Small hosting, VPN nodes, mail servers
/23	512	Growing VPS or shared hosting
/22	1,024	Dedicated hosting, multi-region
/21–/18	2K–16K+	Large hosting, cloud, ISPs

Also consider:

Geography — Do you need IPs in a specific region for reputation or compliance?
Duration — Month-to-month or multi-year?
Reputation — Do you need clean IPs with strong deliverability for email or marketing?

This clarity will drive whether you use an IPv4 marketplace or pursue RIR-based options.

Step 2: Choose Your Path—RIR Direct or Marketplace

You can lease IPv4 address blocks in two main ways:

Option A: IPv4 Marketplace

Use a platform like InterLIR Global that connects you with verified lessors. You browse or request blocks, pay, and receive an LOA and routing details—usually within 24 hours.

Best for: Hosting providers who want speed, transparency, and minimal administrative overhead.

Option B: Direct from RIR (RIPE / ARIN)

If you are an LIR (Local Internet Registry) with RIPE or have ARIN resources, you may lease space from other LIRs under RIR policy. This involves more administrative and technical steps.

Best for: Large operators with in-house RIR and routing expertise.

We’ll cover both paths in the steps below.

Step 3: RIPE Region (EU) — How to Lease IPv4 Blocks

For EU hosting providers, RIPE NCC governs much of the address space. Here’s the typical flow when leasing through the RIPE ecosystem:

RIPE NCC membership — You typically need an LIR account or work with a partner LIR.
Identify a lessor — Either via an IPv4 marketplace or a direct agreement with another RIPE member.
RIPE database updates — The lessor configures the RIPE database:
- Create or edit inetnum objects
- Set SUB-ALLOCATED PA for blocks larger than /24
- Add maintainer objects for the marketplace or lessee
- Configure abuse-c and routing maintainers
Ownership verification — RIPE sends a verification email to the organization’s abuse mailbox.
Clear routing — Remove existing route objects, ROAs, and BGP announcements before reassignment.

Policy note: Only PA (Provider Allocated) space can be leased under RIPE policy. PI (Provider Independent) addresses are not eligible for sub-allocation/lease.

Step 4: ARIN Region (US) — Important Considerations

For US hosting providers, ARIN policy is stricter on leasing:

ARIN does not process leasing-based requests — You cannot use leased space to justify new allocations from ARIN’s Waiting List or as the basis for market transfers.
Leased addresses must be recorded as reassignments/reallocations in the RIR Whois database.
Certain blocks (e.g. micro-allocations, critical infrastructure) are never eligible for leasing.

Practical path in the US: Most US operators lease IPv4 through marketplaces or brokers. The commercial terms, LOA, and RIR record updates are handled by the platform. You focus on payment, verification, and routing.

LACNIC (Latin America): InterLIR Global also supports LACNIC resources. If you serve Latin American markets from US or EU infrastructure, marketplace leasing can provide blocks from that region as well.

Step 5: Complete Documentation and Routing Setup

Regardless of path, you’ll need:

Letter of Authorization (LOA) — Gives your upstream permission to accept your BGP announcements.
RIR records — Correct inetnum, route, and optionally ROA objects.
Reverse DNS — Delegation for your blocks if you provide rDNS.

On a marketplace like InterLIR Global, LOA and basic routing objects are typically provided automatically. For direct RIR arrangements, your lessor or LIR partner handles these updates.

Step 6: Verify and Announce Your Prefix

Verify LOA — Confirm the LOA matches your contract and ASN.
Configure BGP — Announce the leased prefix from your border routers.
Test connectivity — Ensure your upstream accepts the route and traffic flows.
Set up reverse DNS — If required for your services (e.g. mail).

Most marketplaces deliver LOAs and network details in under 24 hours, so you can go from signup to live announcement quickly.

Pricing and Market Context for 2026

IPv4 leasing costs vary by block size, reputation, and region:

Budget tiers — $0.30–0.50 per IP per month for larger blocks
Premium — Higher rates for blocks with strong reputation and clean history

At InterLIR Global, pricing starts at €99 per /24 per month, with no hidden fees. You can rent IPv4 addresses from the marketplace or buy IPv4 if you prefer full ownership.

Summary and Next Steps

To lease IPv4 address blocks in 2026 as a hosting provider:

Define your block size, duration, and geography.
Choose an IPv4 marketplace or direct RIR path.
For EU: work within RIPE policies (PA space, database updates). For US: use marketplaces; ARIN does not support leasing-based justifications.
Obtain LOA and routing documentation.
Announce your prefix and verify connectivity.

InterLIR Global serves hosting providers across the US and EU with blocks from /24 to /16, automated LOAs, and abuse management. Get started to lease IPv4 space in under 24 hours.
