When you buy an IPv4 address, several things happen during the process:

• Verification: Prior to purchase, the IPv4 address block is verified to ensure it is not blacklisted, has no past history of abuse, and is correctly registered to the seller.
• Price negotiation: You'll negotiate the price of the IPv4 address block with the provider, broker, or Regional Internet Registry (RIR) based on factors such as the size of the block, demand, and regional availability.
• Transaction completion: Once you agree on a price, you will complete the transaction by signing a contract, making the payment, and coordinating the transfer of ownership with the relevant RIR.
• Registration update: After the transaction is complete, the RIR will update their records to reflect your organization as the new owner of the IPv4 addresses. You will need to provide the necessary documentation and information for this process.
• Address allocation: The purchased IPv4 addresses will be allocated to your organization, allowing you to assign and use them within your network.
• Network configuration: You will work with your IT team to configure your network devices and systems to use the newly acquired IPv4 addresses. This may involve updating DNS records, configuring routers, and adjusting firewalls, among other tasks.
• Ongoing management: After successfully integrating the IPv4 addresses into your network, you will be responsible for their ongoing management, including monitoring usage, tracking performance, and ensuring security.

Keep in mind that IPv6 addresses are more readily available and future-proof. Therefore, it's recommended to consider implementing IPv6 alongside IPv4 to ensure long-term compatibility and flexibility for your network.

Buying an IPv4 address is an important investment. Use this checklist to make sure you’re making a safe and reliable purchase:

There are several places where IPv4 addresses can be purchased:

• IP address brokers: As an IP broker company we specialize in buying, selling, and leasing IP address blocks. We maintain an inventory of available IPv4 addresses and can help you find a block that meets your needs.
• Internet Service Providers (ISPs): A number of ISPs provide IPv4 address blocks for sale or lease as part of their offerings. To find out about IPv4 address block availability and pricing, get in touch with your existing ISP.
• Regional Internet Registries (RIRs): RIRs manage and allocate IP addresses for specific geographic areas. Although their main focus is on distributing IPv6 addresses, some RIRs might have IPv4 addresses for sale or transfer. The five RIRs include:
  • ARIN (North America)
  • RIPE NCC (Europe, Middle East)
  • APNIC (Asia Pacific)
  • LACNIC (Latin America and the Caribbean)
  • AFRINIC (Africa)
• Private transactions and transfers: In some cases, organizations with spare IPv4 addresses may offer them for private sale or transfer. Keep an eye on online discussion boards, email lists, and professional groups for such possibilities.

Before purchasing IPv4 addresses, verify that the address range is not blacklisted, has no history of misuse, and is registered accurately to the seller. After obtaining the IPv4 addresses, collaborate with your IT staff to incorporate them into your network and ensure they are configured correctly.

Deciding whether to buy or lease IPv4 addresses for your business depends on several factors, including your budget, long-term needs, and growth plans. Here are some key considerations to help you decide:

• Cost: Purchasing IPv4 addresses requires a significant upfront investment, while leasing typically involves a lower monthly or annual fee. Evaluate your budget and financial priorities to determine which option is more suitable for your organization.
• Long-term needs: If your business has stable and long-term requirements for IPv4 addresses, buying may be the better option. On the other hand, if your needs are temporary or fluctuate, leasing provides more flexibility.
• Growth plans: If your business plans to grow or expand its network infrastructure, buying IPv4 addresses may be more cost-effective in the long run. However, if your organization plans to implement IPv6 in the near future, leasing IPv4 addresses can be a more practical short-term solution until the transition is complete.
• Availability: The availability of IPv4 addresses is limited, and it may be difficult to find a large block for sale. In such cases, leasing IPv4 addresses from an ISP or broker might be the only viable option.
• Maintenance and management: When you lease IPv4 addresses, the provider usually handles the maintenance and management of the address blocks. However, when you buy IPv4 addresses, your organization will be responsible for the ongoing management and maintenance of the IP blocks.
• Transferability: Owning IPv4 addresses allows you to transfer, sell, or lease them to other organizations if needed. When you lease IPv4 addresses, you do not have the same level of control and cannot transfer them as easily.

In summary, consider your business's specific needs, financial situation, and growth plans when deciding whether to buy or lease IPv4 addresses. Additionally, it's important to note that IPv6 is the future of internet addressing, and implementing IPv6 alongside IPv4 will ensure long-term compatibility and flexibility for your network.
