As demand for IPv4 space grows worldwide across ISPs, cloud platforms, hosting companies, data centers, and enterprise networks, selling IPv4 space has become a lucrative opportunity. Clean, well-documented address space supported by accurate registry records and a transparent ownership chain is what buyers seek. Faster approvals, easier negotiations, and increased asset value are all advantages for sellers who adhere to a structured application process. The first step to a successful, compliance-ready transfer is submitting a solid IPv4 seller application.
Since each Regional Internet Registry (RIR) enforces different documentation, verification, and transfer policies, the process can be complicated for first-time sellers. In addition to avoiding delays and compliance issues, a well-prepared application shows prospective buyers professionalism. Here’s a thorough, step-by-step guide to successfully submitting an IPv4 seller application.
Gather and Confirm Ownership Records
Sellers must verify that all ownership documentation is correct and comprehensive before submitting an application. This comprises any legal agreements demonstrating control of the IPv4 block, corporate documents, and historical transfer records. One of the most frequent reasons RIRs postpone or reject applications is incomplete or ambiguous ownership documentation.
Typically, the following documents are needed:
• Signed corporate authorization letters
• Proof of company registration
• Prior transfer approvals (if applicable)
• Agreements attesting to acquisitions or mergers involving the IPv4 block
Making sure these documents are correct builds confidence and prevents problems with compliance.
Examine and Update WHOIS Data
Clean, accurate WHOIS data is necessary for a seller application to be successful. Records, such as the organization name, abuse contacts, and routing information, must show who is currently in charge of the IP block. WHOIS entries that are inconsistent or out-of-date may be rejected right away.
Sellers should verify the following:
• Accurate subnet and assignment structures
• Current abuse-c information
• Valid administrative and technical contacts
• Correct organization name
Purchasers are reassured by clean registry data, which also guarantees smooth RIR validation.
Examine ROA Records and Routing History
Prior to making any purchases, buyers assess routing stability. Sellers should make sure there is no history of leaks, hijacking, or inconsistent BGP announcements on the block. RPKI Route Origin Authorizations (ROAs) that are valid enhance credibility and facilitate approval.
Sellers need to examine the following:
• Removal of out-of-date or conflicting route objects
• RPKI status and ROA configurations
• Historical routing paths
A stable routing profile lowers transfer friction and raises a block’s market value.
Perform a Complete Blacklist and Reputation Audit
The desirability of a block is largely determined by its reputation. Issues like malicious automation, botnet footprints, and spam activity may have been inherited by IPv4 ranges. Transparency is ensured and disagreements are avoided late in negotiations with a comprehensive blacklist audit.
Sellers should check major RBLs such as Spamhaus, SORBS, UCEPROTECT, and Barracuda, along with:
• Any associations with malware or fraud
• Historical abuse reports in databases like AbuseIPDB
Early problem solving significantly boosts buyer confidence.
Get RIR-Specific Transfer Data Ready
For seller submissions, each RIR ARIN, RIPE NCC, APNIC, LACNIC, and AFRINIC has its own guidelines. Sellers must be aware of local regulations regarding transfer eligibility, reassignment records, and justification before submitting an application. Accurately filling out the necessary forms avoids needless rejection.
Key tasks include verifying block eligibility, preparing transfer request paperwork, updating necessary registry objects, and reviewing regional inter-RIR transfer policies.
Processing is accelerated by proper regional alignment.
Send in the IPv4 Seller Application
Sellers can formally submit their application through their preferred marketplace or directly through a RIR-supported transfer channel following the completion of documentation, verification, and audits. Applications must be comprehensive, consistent, and backed up by unambiguous proof of compliance and ownership.
Important components include:
• Subnet description and routing status
• Seller identity and organization details
• Supporting ownership documents
• RIR compliance
Strong applications draw in qualified customers and cut down on back-and-forth communication.
