Define requirements
- Define the required prefix, region, contract period, and intended use.
- Decide whether geolocation, route history, IP reputation, and hygiene constraints matter for the workload.

Lease IPv4 addresses
Businesses can lease IPv4 addresses when they need dedicated public address space without purchasing a block. Leasing suits hosting, cloud infrastructure, customer assignments, VPN and proxy services, VoIP, cybersecurity systems, and enterprise networks where stable IPv4 capacity is required for months or years.
IPv4 leasing is a service that gives a business temporary, dedicated rights to use an IPv4 block while ownership remains with the holder. It allows companies to obtain public address space for a defined term, control infrastructure costs, and avoid the larger upfront commitment required for a permanent IPv4 purchase.

| /20 and larger | 4,096+ | €1680/mo | €0.41/mo | View available blocks |
Blocks are available from /24 to /16, with more than 250,000 IPv4 addresses in inventory. Contract terms can range from one month to three years or longer. Reputation, geolocation, route history, blocklist status, and permitted use may also affect subnet selection.
For projects lasting only a few weeks or months, rent IPv4 addresses may provide more flexibility. If the range will become part of permanent infrastructure, buying IPv4 addresses can eliminate recurring lease payments.

Use leased IPv4 for BYOIP in AWS, Google Cloud, and Azure
AWS
A common fit when AWS public IPv4 charges become large enough to justify bringing your own range forEC2,Elastic Load Balancing,NAT Gateway,EKS, orECS.Google Cloud
A good option when you want your own public range in Google Cloud forCompute Engine,GKE,Cloud Load Balancing, orCloud NATinstead of expanding on provider-assigned IPs.Azure
Useful when Azure public IP costs keep growing acrossVirtual Machines,Load Balancer,NAT Gateway, orAzure Firewalland you want a dedicated range under contract.
When does leasing make sense?
Use case 01
Cloud and hosting
Lease when you need address space for BYOIP, customer allocation, or extra capacity now, but do not want to buy a block yet.
Use case 02
VPN and proxy
Teams often lease when range history, dedicated use, and the ability to keep the same space for the contract term matter operationally.
Use case 03
Enterprise networks
A practical option for branch rollouts, infrastructure expansion, or projects that will run for months or years but do not justify a purchase.
Use case 04
VoIP
Providers use leased space for SIP platforms, trunks, and telecom workloads where stable public addressing matters more than short-term flexibility.
Use case 05
Cybersecurity
Useful for internet-facing tools, threat research, and security operations that need dedicated public IP space without taking on a capital purchase.
Use case 06
Marketing infrastructure
Some teams lease ranges for landing pages, campaign infrastructure, and ad operations where stable public IP allocation is part of the setup.
Leasing is practical when address space is required for stable operations but permanent ownership is unnecessary. It can support cloud BYOIP, hosting, SIP platforms, customer pools, enterprise expansion, and security infrastructure.
A leased range can also be used with supported BYOIP solutions when the cloud platform, prefix, and routing configuration meet the required conditions.
Before signing, review renewal rules, notice periods, permitted use, replacement conditions, and the procedure for returning the block.
Lease vs buy vs rent
| Feature | Lease | Buy | Rent |
|---|---|---|---|
| Ownership | No — holder retains | Full — RIR transfer to you | No — holder retains |
| Upfront spend | Usually none | High one-time payment | Usually none |
| Typical term | Months to years | Permanent | Usually shorter |
| Recurring cost | Monthly or quarterly | None after purchase | Monthly |
| Flexibility | Moderate — renew or return | Low — you own it | High — short commitments |
| Best for | Stable use without purchase | Long-term infrastructure | Short-term demand |
Why lease instead of buying?
Buying ties up budget
If you need addresses for operations, not as an asset, leasing keeps cash free for the rest of the business.
Purchases take longer to close
Buying usually means a formal RIR transfer. Leasing is lighter operationally, so you can often get into service faster.
Demand may change
Not sure how long you’ll need the addresses? Leasing gives you flexibility to scale up or down at renewal.
Once the block is live, treat it as leased inventory, not as space you own. Track the return date, who may announce it, and who owns geofeed and reputation — the operational checklist is in IPAM for leased space.
Frequently asked questions
What is the smallest IPv4 block available for lease?
Most requirements start with a /24, which contains 256 IPv4 addresses. Larger blocks up to /16 are also available.
How long can an IPv4 lease last?
Terms can start from one month and extend to three years or longer, depending on the agreement.
Does leasing transfer ownership?
No. The holder keeps ownership, while the lessee receives the right to use the range during the contract term.
Can leased IPv4 be used for BYOIP?
Yes, where the cloud provider, prefix, routing configuration, and authorization requirements support BYOIP.
