Introduction, IPv4 Scarcity Requires Strategic Decisions
IPv4 address exhaustion has fundamentally changed how organizations acquire public IP address space. Where IPv4 addresses were once assigned directly and quickly, today companies must carefully choose between leasing IPv4 space or becoming a RIPE NCC member to request allocations themselves.
At first glance, RIPE NCC membership may appear attractive due to direct control and long term ownership. However, once membership fees, waiting lists, and upfront sunk costs are taken into account, leasing IPv4 often proves to be the more practical and economical choice, especially for smaller deployments.
This article compares leasing a /24 IPv4 block with becoming a RIPE NCC member, focusing on cost, timing, control, and long term strategic considerations.
What Is RIPE NCC Membership
The Role of RIPE NCC
RIPE NCC is the Regional Internet Registry responsible for managing IP address space in Europe, the Middle East, and parts of Central Asia. Organizations that become members, also known as Local Internet Registries, can request IPv4 and IPv6 resources directly from RIPE NCC.
Membership allows organizations to manage their own address space, configure routing security, and maintain full autonomy over their internet number resources.
RIPE NCC Membership Costs
Under the current RIPE NCC Charging Scheme, becoming a member involves the following costs:
- a one time sign up fee of 1,000 euros
- an annual membership fee of 1,800 euros
To receive an initial IPv4 /24 allocation, new members must first join the IPv4 waiting list. During this waiting period, the organization must remain an active paying member.
The waiting time is typically around two years, during which no IPv4 address space is usable.
Total Cost to Obtain the First /24
Over the first two years, the total cost is:
- year one membership fee, 1,800 euros
- year two membership fee, 1,800 euros
- one time setup fee, 1,000 euros
This results in a total of 4,600 euros paid before receiving the first /24 IPv4 block.
After the allocation is received, the organization continues paying 1,800 euros per year to retain membership and keep the address space, subject to future changes in RIPE NCC billing schemes.
This makes the initial cost a sunk investment with delayed return.
Leasing IPv4 Address Space
How IPv4 Leasing Works
IPv4 leasing allows organizations to rent address space from providers that already hold IPv4 allocations. The addresses are routed to the customer and can be used immediately, without becoming a RIPE NCC member.
A typical market price for leasing a /24 IPv4 block is:
- 119 euros per month
- 1,428 euros per year
There are no setup fees, no waiting lists, and no long term contractual obligations in most cases.
Cost Comparison Between Leasing and Membership
For a single /24 IPv4 block, the cost comparison looks as follows:
- RIPE NCC membership costs 4,600 euros over the first two years, with no usable IPv4 during the waiting period
- IPv4 leasing costs 2,856 euros over two years, with immediate usability
After the waiting period, RIPE NCC membership continues to cost 1,800 euros per year, while leasing remains at approximately 1,428 euros per year.
From a purely financial perspective, leasing remains cheaper for at least the first several years.
Operational Control and Flexibility
Benefits of RIPE NCC Membership
RIPE NCC membership provides:
- full administrative control over IP address space
- direct access to RIPE database management
- native RPKI and routing policy control
- independence from third party leasing providers
This level of control is particularly valuable for internet service providers, network operators, and organizations with strict routing or compliance requirements.
Advantages of Leasing IPv4
Leasing IPv4 offers:
- immediate availability of address space
- lower upfront costs
- predictable monthly expenses
- flexibility to scale up or down
For hosting companies, SaaS platforms, startups, and short term projects, leasing aligns well with operational and financial flexibility.
IPv6 as a Strategic Factor
IPv6 Allocation Through RIPE NCC
An important advantage of RIPE NCC membership is access to IPv6 address space. Members can request an IPv6 allocation, typically ranging from a /29 to a /32.
There is no additional cost for IPv6 allocation, no waiting list, and no need to lease IPv6 separately.
For organizations deploying IPv6 or planning a transition, this can significantly improve the overall value of membership.
When RIPE NCC Membership Makes Sense
Becoming a RIPE NCC member is generally justified when one or more of the following apply.
Full and Permanent Control Is Required
Membership is suitable if you need:
- complete ownership and control of IP resources
- long term routing stability
- independence from commercial leasing arrangements
Native IPv6 Is a Priority
If your infrastructure requires:
- permanent IPv6 address space
- no recurring IPv6 leasing costs
- direct resource management
RIPE NCC membership becomes more attractive.
Multiple IPv4 /24 Blocks Are Involved
Membership can also make sense if you are acquiring multiple IPv4 /24 blocks via the transfer market. In this case, the annual membership fee is spread across more address space, lowering the effective recurring cost per /24.
This does require a higher upfront investment, but can be cost efficient for larger operators.
When Leasing IPv4 Is the Better Option
Leasing IPv4 is usually the better choice if you:
- only need one or a small number of /24 blocks
- require immediate deployment
- want to avoid large upfront costs
- operate in a dynamic or short term environment
For many organizations, leasing remains the most economical and operationally simple solution.
Conclusion, Choosing the Right Strategy
The decision between leasing IPv4 and becoming a RIPE NCC member should be based on strategy rather than sentiment.
Leasing IPv4 offers speed, flexibility, and lower short to medium term costs. RIPE NCC membership offers autonomy, native IPv6, and scalability, but requires a significant upfront investment and patience.
For a single /24 IPv4 block, leasing is usually the rational choice. For long term growth, IPv6 adoption, or ownership of multiple IPv4 blocks, RIPE NCC membership can become strategically sound.
Aligning your choice with your technical needs and financial horizon is the key to making IPv4 scarcity work in your favor.
