Most people budgeting for an IPv4 deal look at the market price — $30 to $60 per address on a /24 block — and stop there. That’s a mistake. Between registry fees, brokerage cuts, and compliance work, the “real” cost of a transfer can climb by thousands of dollars, and I’ve watched more than one buyer get blindsided by it. Each RIR handles this differently, too: ARIN, RIPE NCC, APNIC, and LACNIC all have their own fee schedules, review processes, and timelines. If you’re planning a purchase, a merger, or just moving blocks around inside your own organization, those differences matter.
Why IPv4 Transfer Fees Matter More Than You Think
On paper, the registry fee looks like a rounding error next to a six-figure purchase. But it shapes your timeline, your legal exposure, and your total cost of ownership. A transfer that stalls can push back a service launch by weeks. A sloppy paper trail? That can trigger a post-transfer audit — or worse, a reclaim proceeding. There’s also a signal buried in the fees themselves: registries that charge more tend to review more rigorously. Cheap and fast usually means lighter scrutiny, not a better deal.

ARIN Transfer Fees: Simplicity at a Premium
ARIN keeps it flat. One fee per transfer, regardless of block size, which makes it arguably the most predictable registry to deal with.
Current ARIN Structure
- Specified transfer fee: around $500 per transfer, size doesn’t matter.
- Reserved transfer (ARIN-managed escrow): a higher tier, roughly $1,000, for parties who want ARIN holding the documentation.
- M&A transfers: billed under ARIN’s M&A fee schedule, scaled to organization size.
- Annual fees: the recipient picks up ongoing maintenance based on block size — a /24 currently runs in the neighborhood of $250/year.
Timeline
Clean paperwork, and you’re looking at 1 to 4 weeks. Legacy resources or a shaky chain of custody will stretch that out. Sometimes considerably.
RIPE NCC Transfer Costs: Membership Matters
Here’s the thing about RIPE NCC: there’s no per-transfer fee between LIR members. Instead, the receiving organization has to be an Extended Registration Key holder or an LIR member — and that status comes with its own price tag.
Key Cost Components
- LIR membership: new members pay an entry fee (somewhere in the €2,000–€3,000 range) plus an annual fee of roughly €1,400–€2,000 depending on tier.
- Independent Internet Resources (legacy) holders: transfers to non-members may require new RIPE NCC agreements and the fees attached to them.
- Sponsorship costs: plenty of buyers go through a sponsoring LIR instead, which adds annual sponsorship fees of €300–€900.
Timeline
Expect 1 to 3 weeks — assuming both sides submit complete Transfer Request Forms and can document the underlying agreement. Half-finished forms are where these deals quietly die.
APNIC Transfer Fees: Usage-Based Approach
APNIC ties its fees to the account structure and how much space you’re actually moving.
- Transfer fee: a modest administrative charge (hundreds of USD) for inter-RIR and intra-RIR transfers.
- Membership fees: recipients typically become APNIC members or non-member account holders, with annual fees that scale to holdings.
- Demonstrated need: for most transfer types you’ll have to justify utilization — generally 25% immediate use, 80% within 12 months in certain scenarios.
Most APNIC transfers close in 2 to 5 weeks. Need-validation is, more often than not, what slows things down.
LACNIC Transfer Fees: The Highest Friction
LACNIC is the strictest of the four, and the fee structure tells you as much.
- Transfer fees: charged per block and scaled by prefix size — often $1,000–$3,000+ for larger blocks.
- Eligibility limits: recipients may hit caps on how much space they can receive, and both parties face strict documentation requirements (notarized or apostilled documents in some countries).
- Timeline: plan on 4 to 10 weeks. Cross-border authentication of legal documents pushes it longer.
Side-by-Side Comparison of IPv4 Transfer Fees
| Registry | Typical Transfer Fee | Extra Costs | Timeline | Policy Friction |
|---|---|---|---|---|
| ARIN | ~$500 flat (up to ~$1,000 reserved) | Annual maintenance fees | 1–4 weeks | Low |
| RIPE NCC | No direct fee; membership required | Entry + annual LIR fees, or sponsoring LIR | 1–3 weeks | Low–Medium |
| APNIC | Hundreds of USD | Membership/non-member account fees | 2–5 weeks | Medium (need-based) |
| LACNIC | $1,000–$3,000+, size-based | Notarization, legal documentation | 4–10 weeks | High |
And the registry is only part of the picture. Budget for brokerage or marketplace fees (typically 3–10%), legal review ($1,500–$5,000), and RPKI/ROA configuration work. A $500,000 acquisition can easily carry $15,000–$30,000 in ancillary costs. People forget that.
Practical Tips to Reduce Transfer Costs and Delays
- Pre-clear documentation: get bills of lading for legacy space, corporate registrations, and proof of signing authority together before you list or bid.
- Bundle blocks strategically: ARIN’s flat fee rewards combining adjacent blocks into a single transfer where policy allows.
- Check recipient eligibility early: APNIC need justification and LACNIC caps have disqualified buyers after money changed hands. Don’t be that buyer.
- Use escrow: reputable marketplaces hold funds until the RIR confirms, which protects both sides.
- Negotiate fee allocation: splitting registry fees 50/50 is standard, but sellers often eat them to close faster. Worth asking.
Frequently Asked Questions
Who pays the IPv4 transfer fee, buyer or seller?
Whatever you negotiate. Splitting evenly is the most common arrangement, but in a buyer’s market sellers frequently absorb the whole thing.
Can I transfer IPv4 addresses between regions?
Yes. All four RIRs support inter-RIR transfers under their own policies — though cross-region moves mean extra documentation, and APNIC adds need-validation on top.
Are there fees to receive IPv4 space for free (e.g., via merger)?
M&A transfers usually carry lower or different fees than specified transfers, but the annual resource fees always land on the recipient.
What’s the biggest hidden cost in an IPv4 transfer?
Delays. A stalled transfer postpones service launches and revenue recognition, and a broken chain-of-custody trail can void a deal even after escrow has been released.
Conclusion
Each registry has its own personality, in a way. ARIN is the most predictable. RIPE NCC rewards you if you’re already an LIR. APNIC balances moderate fees against need-based validation, and LACNIC will test both your budget and your patience. Whichever one governs your deal, the total cost goes well beyond the sticker price of the addresses themselves. Compare fees, timelines, and policy friction before committing — and transact through a trusted platform with verified sellers and competitive pricing. That’s the surest way to protect both your budget and your routing integrity.
