IPv4 leasing gives a business temporary use of address space for a recurring fee, while buying IPv4 provides permanent ownership or transfer rights to the address resources. Leasing generally requires less upfront capital and offers more flexibility, while purchasing may make sense for organizations that need long-term control over a significant IPv4 portfolio.
The better choice depends on how long the addresses are needed, how much capital the business wants to commit and what network infrastructure is required around them.
Why Businesses Still Need IPv4
IPv6 continues to expand, but IPv4 remains deeply embedded throughout the Internet.
Businesses may still require public IPv4 addresses for:
- Internet-facing servers
- SaaS applications
- Network infrastructure
- Enterprise VPN systems
- Web-data platforms
- Monitoring systems
- Cybersecurity research
- Private cloud environments
- Legacy applications
- IoT deployments
- Disaster-recovery infrastructure
Because freely available IPv4 space has largely been exhausted, businesses needing additional addresses generally must lease or acquire them from organizations that already control address resources.
What Is IPv4 Leasing?
IPv4 leasing allows a business to use address space without permanently acquiring it.
The business typically pays a recurring monthly or annual fee.
Depending upon the provider, the lease may include only the address resources or may be combined with:
- Routing
- BGP
- Bandwidth
- Reverse DNS
- Colocation
- Power
- Network engineering
- Monitoring
- Remote hands
IPv4 leasing is often attractive when a company needs flexibility or wants to avoid a large upfront purchase.
What Does Buying IPv4 Mean?
Buying IPv4 generally involves acquiring permanent rights to a block of address resources through an approved transfer process.
Purchasing can provide long-term control, but it also requires significant upfront capital.
The buyer may also need to handle:
- Registry transfer procedures
- Routing
- BGP
- Network integration
- RPKI
- Reverse DNS
- Geolocation updates
- Reputation review
- Upstream connectivity
Buying the addresses does not automatically create the infrastructure needed to use them.
IPv4 Leasing vs. Buying at a Glance
| Factor | Leasing IPv4 | Buying IPv4 |
|---|---|---|
| Upfront Cost | Lower | Higher |
| Monthly Cost | Recurring | Usually infrastructure only after purchase |
| Permanent Ownership | No | Yes |
| Flexibility | High | Lower |
| Easy to Scale | Often | Requires additional purchases |
| Capital Requirement | Lower | Significant |
| Temporary Projects | Good fit | Often unnecessary |
| Long-Term Portfolio | Less ideal | Stronger fit |
| Provider Infrastructure Available | Often | Usually separate |
| Exit Flexibility | Higher | Lower |
When IPv4 Leasing Makes Sense
Leasing can be attractive when:
You Need IPv4 Quickly
Purchasing and transferring address space can involve more complexity than leasing an existing allocation through an established provider.
You Want to Preserve Capital
Leasing converts a large upfront investment into a recurring operating expense.
That can be useful for businesses that would rather invest capital in servers, software, staffing or growth.
Your Requirements May Change
A company may need a /24 today and a /22 later.
Leasing can offer more flexibility to expand, reduce or change infrastructure over time.
You’re Testing a New Deployment
A business launching a new platform may not want to permanently purchase thousands of addresses before proving the business model.
You Need More Than Just Addresses
Leasing through a network operator may allow the company to obtain:
IPv4 resources + routing + bandwidth + colocation + technical support.
That can simplify the overall deployment.
When Buying IPv4 May Make Sense
Purchasing may be appropriate when:
IPv4 Is a Permanent Strategic Requirement
Organizations expecting to require the same address resources for many years may prefer direct control.
The Organization Has Significant Capital Available
Buying requires a larger upfront commitment but eliminates recurring address-lease payments.
The Company Wants Full Address Control
Organizations operating their own autonomous system and infrastructure may prefer owning the resources directly.
IPv4 Is Part of a Long-Term Asset Strategy
Public IPv4 address space is scarce.
Some organizations view ownership as a strategic network asset rather than simply an operating requirement.
The Hidden Cost: Infrastructure
One of the biggest mistakes when comparing leasing and purchasing is looking only at the address cost.
IPv4 resources still need a network.
A business may also need:
- Internet bandwidth
- BGP routing
- ASN integration
- Servers
- Racks
- Power
- Cooling
- Firewalls
- Switches
- Reverse DNS
- Monitoring
- Technical support
- Abuse handling
That can make the network surrounding the IPv4 allocation just as important as the addresses themselves.
Buying IPv4 Does Not Automatically Mean Better IP Reputation
An IPv4 block can have years of history before it changes ownership.
Purchasing address space therefore does not automatically guarantee a clean reputation.
Before deploying purchased or leased resources, businesses should consider:
- Spam history
- Blocklist status
- Prior hosting use
- Proxy history
- Abuse reports
- Geolocation
- Routing history

IPv4 Leasing Through a Marketplace vs. a Network Operator
An IPv4 marketplace may primarily provide access to address resources.
A network operator can potentially provide the infrastructure behind them.
NetWest’s managed approach can combine:
- Dedicated IPv4 resources
- ISP network routing
- BGP
- Bandwidth
- Colocation
- Power
- Reverse DNS
- Remote hands
- Network engineering
That creates a different value proposition from simply obtaining the lowest possible price per address.
Which Option Is Better?
There is no universal answer.
Consider these questions:
How long will you need the addresses?
Shorter or uncertain deployments generally favor leasing.
How much capital do you want to commit?
Leasing lowers upfront cost.
Do you operate your own network?
Organizations without extensive network infrastructure may benefit from managed services.
Do you need to scale?
Leasing can provide flexibility when requirements are growing or changing.
Do you require permanent control?
Buying may be more appropriate.
Do you also need servers, bandwidth or colocation?
A managed infrastructure provider may simplify the deployment.
Example: Leasing a /22
Suppose a business requires approximately 1,000 IPv4 addresses.
A /22 contains 1,024 total IPv4 addresses.
The company could purchase its own /22 and then separately arrange routing, bandwidth and hosting.
Or it could lease a /22 as part of a managed deployment that includes the network infrastructure required to operate it.
The right decision depends upon duration, capital requirements and operational capability.
