Lease IPv4 /24, Routable Blocks, Ready in 24 Hours

By Savvas Bout, Founder of Prefixx. Last updated 24 September 2026.

Reputation-free IP space, or if a BGP announcement needs a dedicated IP prefix that you don’t yet own. Leasing a /24 for hosting gives you all of these without having to spend money or wait months for a purchase to transfer. Organizations that lease IPv4 24 blocks gain immediate routing capability without the capital outlay or administrative overhead of ownership transfer.

Leased /24 network space is offered for 256+ usable IP addresses from your own ASN with full control, RPKI enabled and clean abuse history. Note that you are only paying for usage rights as opposed to purchasing space for which you will retain ownership. The economics work well for short term needs or for situations where various factors make cash preservation more important than IP address space equity.

The leasing model addresses the constrained global supply by making existing allocations available without requiring permanent acquisition. The leasing model allows a company to deploy routable address space quickly while preserving capital for other operational priorities.

This article delves into the specifics of /24 IPv4 leasing arrangements, how they work at the registry and routing layer. What you should verify before you sign on the dotted line, a look at the lease economics versus purchasing outright over different time horizons. A thorough understanding of these arrangements will help you make a complete assessment of whether leasing fits your infrastructure strategy.

Additionally, what exactly white-glove support from a specialist lease broker looks like. We'll start by explaining what a /24 is and why choosing to lease IPv4 space has become the default method for companies with fast-moving Internet requirements to get a hold of large amounts of routable space. For community perspectives, see IPv4 Leasing : r/networking . Detailed documentation and guidance are typically available on the broker's website to help clients understand the leasing process.

What is a /24 IPv4 block and why lease IPv4 addresses

A /24 is 256 contiguous public IPv4 addresses announced as a single routing prefix. The smallest block size that most transit providers will accept in BGP for independent routed IP space is a /24. This prefix size ensures global reachability across transit providers in any geographic region. This prefix size guarantees that your infrastructure will have reliable global access through any major transit network. This prefix size is particularly important for organizations running distributed infrastructure across multiple data centers or cloud environments.

Why the /24 is the default lease unit for IPv4 addresses

In IPv4 leasing, BGP routing table limits mean blocks smaller than a /24 are typically discarded by upstream providers of your hosting provider.

When free pools run out of IP month after month

There are only 4.3 billion available IPv4 addresses and the five RIRs have closed their free pools of IPv4 addresses between 2011 and 2020. Leasing IP addresses has become a secondary market activity and no longer a service provided by IP registries.

Lease IP addresses with strong IP reputation and clean boundaries

Leased IP is rented in a dedicated block to keep your IP reputation separate from other Prefixx tenants. The provider will verify that the block is clean and has no prior blacklist history before assignment to your infrastructure. Each leased block is assigned exclusively to a single client, ensuring that no other company shares the same address space during the lease term.

In addition to leasing IP for connectivity, we provide a white-glove service for reputation monitoring of all blocks you lease, scanning for listing on blacklists. In addition to explaining the process and pricing for leasing a /24 in detail, we outline the agreement and BGP announcement of leased IPs in a subsequent article. If you notice any reputation issues with your leased block, you can contact our support team for immediate remediation assistance.

How IPv4 leasing works: from agreement to announcement

Renting IPv4 addresses enables a lessee to use a block for routing while the lessor holds title. The lessor is listed as the registered holder with the relevant RIR while the lessee advertises the IP addresses from his or her own routing table using his or her own AS number.

The lessee maintains operational control over how the addresses route and how systems respond to traffic directed at those addresses. This arrangement provides the lessee with full routing authority and operational control, granting them the same level of network access they would have if they owned the block outright.

BGP routing and the LOA

After signing the lease agreement, you receive a Letter of Authorization enabling you to announce the announced prefix from your own ASN via BGP. In the IRR, matching route objects are created and WHOIS updates the respective routing policy. Optionally, an RPKI ROA is registered for your origin-ASN network addresses to fix hijacking.

Ptr records and rdns delegation

For /24s and larger sizes, the lessor can delegate the reverse DNS zone for you to the nameservers of your choice. You can then manage rDNS directly on your system and create PTR records for individual hosts. Support for this is part of Prefixx’ white-glove service and also includes geolocation updates for major providers which are pushed daily via a RFC 8805 geofeed.

What you get versus what you own network

Half of understanding your rights is knowing what you're paying for in a lease, whether you can cancel anytime, and how the various costs and constraints affect the overall price. A clear lease agreement should outline exactly what the monthly or annual plan includes and any restrictions on usage or transfer.

What a /24 lease term costs and what moves the price

The cost per IP month for a leased 256-address /24 block can vary greatly depending on the registry where it is housed, the cleanliness of the block, and the length of your commitment. Typical monthly prices for a /24 in the IPv4 leasing market range from $112/month to $350/month based on current market data. Registry location can influence pricing because transfer policies and administrative overhead differ across RIRs.

What moves the number

1. By Registry region, ARIN and RIPE NCC traded blocks at different price points throughout the month while Asia Pacific demand pushed APNIC pricing to even higher levels given the large number of regional customers unable to source IP address space locally.
2. Block Reputation: Blocks with a clean standing and no blacklisted hits command a premium. Blocks with a history of spam lease for less, if they lease at all.
3. The length of the lease term. Flexibility to go month-to-month will typically cost you more per IP than a commitment of a certain term or more. Lessors have more stable income when they have committed terms, and they will pass on some of that to you in the lease terms for longer term commitments.
4. The bigger block size often results in a lower IP address price per IP. A /22 will usually even be cheaper per IP than a /24 from the same supplier.

What to watch for with IPv4 addresses

1. Bundled services. Many providers strip out routing work and charge for it separately. For all services that Prefixx provides as part of a lease, that would include LOA, RPKI ROA, IRR objects, and lots of white-glove support.

Note: Never accept a lease without a non-revocation guarantee in writing. Without it, the lessor can pull the lease IPv4 addresses block mid-contract and leave your infrastructure unreachable. The guarantee also protects against scenarios where the lessor might attempt to reclaim addresses due to alleged misuse or other disputed grounds.

Cost is only one factor to consider when weighing up the pros and cons of hiring as opposed to buying outright. The primary advantages of leasing include lower upfront capital requirements and the flexibility to return space when it is no longer required.

Leasing vs buying a /24: which makes sense

Leasing versus buying a /24 IP address block depends on your business needs and how long you think you will need the IP addresses. It comes down to the amount of capital you have, how soon you need the IP addresses, and how sure you are that you will need them in the long term. Evaluating these factors carefully will help you decide whether a lease or purchase aligns better with your infrastructure strategy.

The case for leased IPs

Renting a block of IP addresses (a /24) allows you to keep upfront costs low. We can help you lease IPv4 addresses with a routable /24 block delivered within 24 hours, all paperwork handled by the RIR for the transfer on your behalf.

Our flexible terms to lease IPv4 addresses allow you to scale up or drop out as you need to, without locking your capital in a physical asset. Should demand plummet, you can simply cancel your rental agreement rather than be left holding a block of IP addresses you no longer need.

This flexibility is particularly valuable for customers whose infrastructure requirements fluctuate seasonally or who are testing new services before committing to permanent address allocations. This flexibility proves especially useful for organizations deploying temporary infrastructure in cloud environments where resource allocation changes frequently.

Leasing is ideal for short-term projects (e.g. migrating hosts), uncertain workloads, etc. Prefixx takes care of LOA, RPKI ROA, and IRR objects for your IPv4 leasing needs, so your IP forwarding is ready when you need it. For more context, see IP address.

The case for buying data centers

Transferring ownership of a resource via buying allows you to take full control of it and have it be registered in the RIR database under your organization. For long-term stable network infrastructure, buying allows you to get rid of recurring costs after the transfer has taken place.

The key trade-off here is with capital, the cost to buy a /24 is a multiple of the annual cost to lease. Leasing would likely cost less had you exited prior to that point.

Which path fits your situation

A long term commitment to a fixed address range, with no plan to exit, favors buying. Leasing addresses the needs of businesses with shorter horizons, budget constraints, or uncertain network growth. Prefixx handles both, and our /lease-vs-buy page walks through the financial mechanics in detail.

Our team can also support you in modeling break-even against your actual usage timeline. Whichever path you choose in IPv4 leasing or outright acquisition, the quality of the block itself matters just as much as the economics, and that starts with history due diligence.
