Common Mistakes in IPv4 Transfers

Transferring IPv4 addresses can be a complex process. Between Regional Internet Registry (RIR) requirements, contract details, and technical steps, there are many opportunities for errors that can delay or even derail a transaction. Whether you’re buying, selling, or leasing IPv4 addresses, understanding the most common mistakes can save you time, money, and frustration.

Here are some of the top pitfalls organizations encounter during IPv4 transfers, and how to avoid them.

IPv4 Transfer Mistakes & Why You Should Use a Broker

1. Incomplete or Outdated RIR Records

One of the most frequent mistakes is failing to keep RIR records accurate and up to date. If your organization’s contact details, registration agreements, or allocation data are not current, the transfer may be delayed or rejected.

It’s especially important for the Seller in an IPv4 transaction to make sure their organization’s company details in the RIR system are current and reflect an actively registered company. All RIRs check the online division of corporations’ websites to make sure the company is still active and doing business. If your company was acquired or merged since its original RIR registration, you may have to go through a process to update those records with the RIRs before selling your IPv4 addresses.

How to avoid it:
Review and update your records with ARIN, RIPE NCC, APNIC, LACNIC, or AFRINIC before beginning a transfer. Confirm that all organizational information is consistent and compliant.

2. Skipping Pre-Approval Requirements

Certain RIRs, such as ARIN and APNIC, require buyers to demonstrate justified need for IPv4 addresses before approving a transfer. Many transactions stall because recipients fail to secure this pre-approval in advance.

How to avoid it:
Check the specific requirements of your RIR before beginning a transaction. If justification is required, prepare documentation of current usage and projected growth to expedite approval. Perform the pre-approval process BEFORE engaging in an IPv4 purchase so your funds aren’t needlessly tied up in escrow.

3. Overlooking Contractual Protections

Some organizations enter transfers without a strong contract in place. This exposes both buyers and sellers to risks such as payment disputes, unclear responsibilities, or fraud.

How to avoid it:
Always use a detailed purchase or lease agreement that clearly defines responsibilities, payment terms, and compliance obligations. Partnering with a reputable broker ensures professional documentation and secure transactions.

4. Ignoring IP Reputation

IPv4 addresses that have been blacklisted or associated with malicious activity lose value and may be unusable for certain purposes. Failing to check reputation before purchasing can result in wasted investment.

How to avoid it:
Perform a thorough reputation check on all IP addresses involved in the transaction. Work with brokers who vet address space and guide you on remediation if issues are found.

5. Underestimating IP Transfer Timelines and Fees

Each RIR has different fees, timelines, and approval processes. For example, ARIN typically requires more detailed reviews, while RIPE NCC often processes transfers faster. Not accounting for these differences can cause budgeting and planning issues.

How to avoid it:
Understand the specific policies of your RIR before starting the process. Factor in fees, documentation requirements, and expected timelines. An experienced broker can help you anticipate these differences and plan accordingly.

6. Attempting DIY IPv4 Transfers Without Expertise

Many businesses underestimate the complexity of IPv4 transfers and attempt to handle them alone. Without knowledge of RIR policies and market dynamics, this can lead to costly mistakes.
