Why the Real Cost Bites
Nobody talks about the fees. Everyone focuses on the price per IP. “Twenty-five bucks an IP? That’s a steal!” And then the bill comes. Broker commission. RIR fee. Escrow. Legal review. Suddenly that “steal” looks a lot less sexy. I’ve seen deals where the add-on costs hit 30% of the total. Not fun. So let’s cut through the noise and look at what you’re actually signing up for.
Breaking Down the Bill
It’s never a single wire transfer. A bunch of hands get in the pot. Here’s how the cash usually flows:

1. The Middleman’s Cut
Whether you go through a broker or a marketplace, someone takes a service fee. Old-school brokers? They’ll skim 10–15% right off the top. A marketplace like IP4 Market takes a different approach—flat fee, no percentage games. I prefer knowing exactly what I’m paying before I sign anything. Don’t you?
2. What the RIR Charges
Then the regional registry wants its piece. Every region has its own fee schedule, and it shifts depending on block size. One of those “love it or hate it” realities. Here’s a rough idea of what you’ll see:
| RIR | Fee per transfer (up to /24) | Fee for larger blocks |
|---|---|---|
| ARIN | $500 – $1,500 | $1,500 – $5,000 |
| RIPE NCC | €0 – €500 | €500 – €2,000 |
| APNIC | $100 – $500 | $500 – $2,000 |
| LACNIC | $200 – $800 | $800 – $3,000 |
3. Escrow and Legal Review
You wouldn’t hand a suitcase of cash to a stranger. Escrow is the safety net. Costs 1% to 3% of the transaction—better than losing the whole thing. Legal due diligence, verifying ownership, checking blacklists? That adds another $500 to $2,000, depending on how deep you want to dig.
4. Tech Setup
Once the deal clears, you’ve got to update WHOIS, set up route objects, maybe pay a small admin fee to your LIR or ISP. Usually $100 to $400. Small stuff, but it adds up.
What the Market Looks Like Right Now
So what’s the baseline? Here’s where the numbers sit as of mid-2025:
| Block Size | Average Price per IP | Total Range | Typical Transfer Fee (All-in) |
|---|---|---|---|
| /24 (256 IPs) | $25 – $35 | $6,400 – $8,960 | $1,200 – $2,500 |
| /23 (512 IPs) | $22 – $30 | $11,264 – $15,360 | $2,000 – $4,000 |
| /22 (1024 IPs) | $20 – $28 | $20,480 – $28,672 | $3,500 – $6,500 |
Bigger blocks give you a lower per-IP price, but those RIR volume charges climb right along with the size. Always ask for the full breakdown. Every single time.
What People Often Miss
This is the part that trips people up. A few things slip through the cracks:
- Premium routing status: A “clean” block (no blacklists) can command a 10–20% premium. You pay for reputation.
- Expedite fees: Need it in five business days? Some RIRs will tack on an extra $1,000 or more for the rush.
- Fragmentation penalties: Non-contiguous blocks can come with higher RIR processing fees.
- Withdrawal costs: Deal falls through? Some brokers keep a non-refundable deposit—5–10% of the block price.
Five Ways to Keep More of Your Cash
- Stick with transparent platforms: IP4 Market shows you broker, RIR, and escrow fees right on each listing. No surprises at the end.
- Bundle your transfers: Buying multiple blocks in one batch? Some RIRs offer discounted handling fees. Ask about volume pricing.
- Shop around on RIR fees: RIPE can be easier on the wallet than ARIN in some cases. Just make sure you meet the needs-based policy.
- Negotiate the escrow rate: Standard is 2–3%. If the deal is north of $50k, push for 1%—it works more often than you’d think.
- Think about leasing: If your need is temporary, leasing lets you skip the transfer fees entirely. Worth considering.
Quick Answers to Common Questions
What’s the real-world fee on a /24?
Expect $1,200 to $2,500, depending on the RIR, escrow, and broker. Always get the line-by-line breakdown.
Can I write these fees off?
Most jurisdictions treat them as a capital expenditure—depreciable. But tax rules vary. Ask your accountant.
Can I avoid broker fees entirely?
Yes, if you find a seller on your own. But verifying ownership and managing the paperwork is risky. Most people pay for the safety net. Platforms like IP4 Market charge a flat, reasonable fee and handle the compliance.
How long does it take?
Typically 2 to 6 weeks. Spring for the expedite fee and you can tighten that to 5–10 business days.
The Takeaway
Look, no one gets into IPv4 transfers for the paperwork. But knowing what you’re up against—the commissions, the RIR charges, the escrow, the gotchas—is half the battle. The other half is using a service that shows you the price up front. Platforms like IP4 Market make that easy. Check out their listings. No hidden markups, no last-minute surprises. Just what you need to get the job done.
