IPv4 Address Rental: How It Works, Costs, Risks, and Best Practices

New customers should mean new revenue, not a large upfront address purchase. IPv4 address rental gives your network public address capacity while keeping capital available for servers, connectivity and growth. With LARUS, you rent directly from the team behind the supply and build on Unlimited IPv4 with Continuity.

Start with the capacity your next deployment needs. Compare the current offer, connect the addresses to your network and keep the same operating partner as your services grow.

What Is IPv4 Address Rental?

IPv4 address rental, also called IPv4 leasing, lets you use a block of public IP addresses for a recurring fee. You put those addresses to work on your network without paying to acquire the block. Your customers can reach the hosted services, applications and endpoints you provide through it.

Why Networks Still Need IPv4 Rental

IPv6 deployment continues, but your customers still need to reach services across IPv4 networks. Renting adds that capacity as demand grows. It also lets you plan IPv6 adoption around your customers and infrastructure instead of delaying an IPv4-dependent launch.

Who Rents IPv4 Addresses?

• ISPs: add capacity for subscribers and new service areas.
• Hosting providers and data centres: bring new servers, virtual machines and customer environments online.
• Cloud and SaaS operators: support public endpoints, customer allowlists and regional deployments.
• Enterprise and VPN networks: plan migrations and dedicated access around a stable network identity.

IPv4 Address Rental vs Buying

The first difference is where your money goes. Renting pays for capacity as you use it; buying commits capital to the block. The deeper difference is who supports continued use when the registry relationship becomes a problem.

Compare the operating decision

Your decision	Rent directly from LARUS	Buy and hold a block
Capital	Keep acquisition funds available for growth.	Pay the acquisition cost upfront.
Expansion	Add leased capacity with your supply partner.	Arrange further acquisitions as demand grows.
Registry relationship	LARUS carries the registry-facing work upstream.	Your organisation carries the direct holder relationship.
Continued use	Choose Continuity alongside your address supply.	A completed purchase does not remove registry dependence.

Is Renting IPv4 Better for a Long-Term Network?

Long-term demand does not make buying the automatic answer. Your business needs addresses that remain useful as customers, locations and applications change. Direct rental with Continuity brings supply and ongoing responsibility together while leaving capital in the business. Compare the full cost over your planning horizon and the support behind the addresses, not just a monthly rate against a purchase price.

What Your Business Gains

Leasing frees acquisition capital for the infrastructure that earns revenue. It gives a growing network a way to add capacity, supports migration periods and brings renewal and expansion into an ongoing service relationship. For the wider comparison, read renting versus buying IPv4 addresses.

How Much Does IPv4 Address Rental Cost?

Use the current IPv4 pricing and plan calculator to compare the block size, lease period and service plan for your deployment. You can work from the current offer instead of an old article's price range.

For a per-address monthly quote, your base rental budget is address count × monthly rate × number of months. Compare the total for the same capacity and period, alongside routing support, reverse DNS and Continuity. The IPv4 lease-rate guide explains how to read the offer.

A /24 contains 256 addresses, a /23 contains 512 and a /22 contains 1,024. These are total block counts; your subnet layout determines how you allocate them. Start with today's deployment and room for the customers you expect next. See the IPv4 block-size guide for larger prefixes and a deployment example.

How IPv4 Address Rental Works

1. Plan the next launch. Bring your address count, deployment location and expected growth. That gives LARUS the context to match supply to the services you want to deliver.
2. Choose your plan. Compare the current price and Continuity options, then select the capacity and support that fit your network.
3. Connect the addresses. Your origin ASN and routing plan help align authorisation, IRR and RPKI/ROA records so other networks can validate your announcement.
4. Put customer services online. Check reachability, reverse DNS, geolocation and the applications your customers use. Keep expansion and renewal with the same operating team.

A Letter of Authorisation (LOA) establishes permission to announce the block; a Route Origin Authorisation (ROA) identifies the authorised origin ASN and prefix length for RPKI validation. They serve different purposes. Coordinating both with your upstream network helps your announcement reach customers as intended. Our IPv4 deployment guide walks through the technical setup.

Why First-Party Supply and Continuity Matter

Your addresses become part of your customers' operations: API allowlists, DNS, VPNs and firewall rules. Replacing them can mean work for every customer connected to your service. Protecting that network identity is a buying decision from day one.

LARUS supplies IPv4 from its own pool and carries the registry-facing relationship upstream. Your team has a direct partner for the addresses and their continued use. Buying a block keeps you dependent on the registry; a broker adds a handoff without automatically taking responsibility for that dependence.

LARUS Continuity draws on Cloud Innovation's court-recognised shareholder position in AFRINIC and its exclusive mandate appointing LARUS to operate its IPv4 estate. Put that institutional strength behind the network your customers rely on. Lu Heng's Note 35 explains the foundation of this approach.

Address the Risks That Affect Your Customers

Routability, reputation and renewal all affect the value of rented addresses. A block can route correctly yet encounter an email filter, an outdated location record or a customer allowlist. Check the applications that matter to your network and keep a clear path to the team that can resolve the issue. Continuity in everyday network operations explains why support after activation matters.

How to Choose an IPv4 Rental Provider

Choose the partner you want beside your team after the addresses arrive. Direct control of supply matters when you need a routing change, more capacity or a renewal decision. A low headline price tells you little about who can act when a customer needs help.

A Shortlist for Your Deployment

• Capacity to grow: the block for your launch and a route to your next expansion.
• A usable network identity: routing authorisation, reputation, reverse DNS and location records suited to your services.
• A clear operating partner: direct responsibility for supply, support and continued use.
• A current commercial offer: the full cost and Continuity plan for your chosen capacity and period.

Bring these goals to LARUS and turn them into a deployment plan. You keep your attention on customers while the team behind your address supply handles the upstream coordination.

IPv4 Address Rental Questions

Can I announce rented IPv4 addresses with my own ASN?

Yes. Plan the origin ASN, prefix and upstream connection with LARUS so the LOA and routing records support your announcement. This lets you bring rented capacity into the network you operate.

What is the minimum block size?

A /24 contains 256 addresses and is a common starting point for public BGP announcements. Select the block around your customer demand and upstream routing plan; the current pricing page shows the available configurations.

Can rental support services I expect to run for years?

Yes. Plan renewal and capacity growth as part of the service from the start. LARUS Continuity is built around continued use, so your choice looks beyond the first activation to the network your customers will depend on next.

How do I compare IP reputation?

Look at the services your customers need to reach, the block's routing history and relevant reputation or blocklist results. Test actual application access before moving live traffic. Reverse DNS and location records deserve the same attention because they shape how other services recognise your network.

How do I start renting IPv4 addresses?

Choose your block size and Continuity plan, then bring your deployment location and routing goals to LARUS. Keep your chosen capacity and Continuity plan together as you move from pricing to your order.

Build Around Your Next Customer

Rent the IPv4 capacity that lets your business grow. Keep your capital working, connect directly to your supply partner and put Continuity behind the network identity your customers depend on.
