Every proxy network runs on IPv4. You can have the smartest rotation logic, the cleanest code, and the best support — but without the raw IP inventory, there's no product. For proxy operators building datacenter, static ISP, or static residential offerings, the question of lease vs buy is a seven-figure decision that determines your margin for years.
This guide is the 2026 state of the IPv4 market for proxy operators: what addresses cost today, how leasing and buying actually work (brokers, RIRs, LIR status, RPKI), the real ongoing costs nobody mentions, and the breakeven math that tells you which makes sense.
You've heard "we ran out of IPv4 in 2011" — that's when IANA exhausted its free pool. Regional Internet Registries exhausted shortly after: ARIN in 2015, RIPE in 2019, APNIC and LACNIC earlier. Since then, every new IPv4 address a proxy operator acquires comes from the secondary transfer market or from leasing.
IPv6 was supposed to solve this. It has not, for proxy networks specifically:
Net result: IPv4 is scarce, expensive, and not going away. A proxy operator's inventory strategy is an IPv4 strategy.
The secondary market has been volatile since 2020. Pricing approximate ranges as of April 2026:
| Region (RIR) | Buy price per IP | Lease price per IP / month | /24 block minimum |
|---|---|---|---|
| ARIN (North America) | $40 – $52 | $0.50 – $0.70 | $10,200 – $13,300 |
| RIPE (Europe) | $38 – $50 | $0.45 – $0.65 | $9,700 – $12,800 |
| APNIC (Asia-Pacific) | $42 – $55 | $0.55 – $0.75 | $10,800 – $14,000 |
| LACNIC (Latin America) | $36 – $48 | $0.40 – $0.60 | $9,200 – $12,300 |
| AFRINIC (Africa) | $35 – $45 | $0.38 – $0.55 | $8,900 – $11,500 |
Prices from broker quotes (IPv4.Global / Hilco, Prefix Broker, IPXO, IPv4 Brokers) averaged over Q1 2026. Actual quotes vary by block size, seller, routing history, and whether the block ships with a clean RBL / reputation record.
Trends visible in the data:
You can't just "buy IPs" from a vendor. Every transfer goes through the regional registry:
Leasing platforms match IPv4 owners (banks, old telcos, cloud providers) with IPv4 users (proxy operators, hosting companies, CDN startups). The two biggest in 2026:
Leasing mechanics:
Scenario: a proxy operator needs 1,024 IPs (/22) in RIPE region, starting January 2026.
Buying pays off somewhere between year 5 and year 7 for a typical /22 in RIPE, accounting for RIR fees and expected residual value. Inputs that shift the breakeven:
Patterns across the industry in 2026:
Whether you lease or buy, operating IPv4 for a proxy network costs more than the IP itself:
Running your own Local Internet Registry (RIPE NCC, ARIN) costs money and requires staff time. RIPE LIR: €1,550/year membership + €50 per sub-allocation. ARIN: sliding scale from $250 (nano) to $32,000/year (XXL holder).
You need an ASN to announce blocks. ARIN charges $550 one-time + annual maintenance. RIPE bundles with LIR. Without your own AS, you announce through an upstream provider — which creates dependency.
Modern upstream providers increasingly enforce RPKI-ROV. Every block you announce needs a signed ROA from the registered holder. For owned blocks: you sign. For leased: the marketplace or upstream signs. Incorrect ROAs = invalid announcements = your block goes dark.
Every IP block gets abuse reports: spam, DDoS, phishing, copyright. An abuse@ mailbox that goes unread ends with Spamhaus listing your whole block. For a proxy network, this is a full-time operations function. Typical cost: $30k – $80k/year for a dedicated abuse desk.
You need real-time monitoring of Spamhaus, Barracuda Reputation, Project Honey Pot, SORBS, and Uceprotect. Standard tools: MXToolbox, Validity (formerly 250ok), IPinfo. Budget $500 – $2,500/month.
When an IP does get listed, someone has to file delisting requests. Some RBLs delist automatically after 24 hours of no further abuse; others need a human request with evidence. Not glamorous, but essential.
Owning IPs doesn't deliver traffic. You need IP transit from Tier-1 providers ($0.30 – $1.50 per Mbps/month for proxy-relevant volumes) or peering at exchanges (capex on colocation + hardware).
| Situation | Buy | Lease | Notes |
|---|---|---|---|
| New proxy business, under $500k ARR | — | ✓ | Preserve capex for product and acquisition |
| Core fleet, stable demand, 5+ year horizon | ✓ | — | Breakeven in year 5-7 plus reputation control |
| Experimental geographic expansion | — | ✓ | Lease 30-90 days, buy if demand sticks |
| Burst capacity (short campaigns) | — | ✓ | Monthly lease scales to zero quickly |
| Strict reputation requirements (enterprise customers) | ✓ | — | Control over who uses each IP is non-negotiable |
| Low-risk standardized workloads | — | ✓ | Marketplace abuse policies align with your policy |
| Private equity or acquisition target | ✓ | — | Owned blocks are balance-sheet assets for valuation |
| Uncertain about IPv6 transition timing | — | ✓ | Lease avoids stranded-asset risk |
Datacenter proxy operators are the textbook buying case. You need large contiguous blocks, stable routing, and reputation control. Customers pay for reliability. SpyderProxy Static Datacenter at $1.50/proxy/month with unlimited bandwidth is built on owned infrastructure precisely because the margins at that price only work when the underlying IPs are owned, not rented.
ISP proxies are hosted in datacenters but registered with residential ISPs. The IPs themselves are typically either (a) owned and SWIP'd to look like residential ranges, or (b) sub-allocated from ISP partners who lease them to you. Pure secondary-market leasing is uncommon here because the ISP registration is the whole value proposition.
Rotating residential doesn't use the IPv4 market at all. Inventory comes from peer-to-peer SDKs installed in consumer apps (paid integrations) or from ISP-level agreements. The economics are completely different — cost per GB of traffic routed, not cost per IP.
LTE IPs come from physical SIM cards attached to 4G/5G modems. You're not buying IPv4 from RIRs; you're paying mobile carriers for SIM plans. Standard math: $15 – $30/SIM/month for an unlimited-data plan, serving 1-4 customer IPs per SIM via rotation.
Three dynamics shaping near-term IPv4 economics for proxy operators:
Secondary market prices run approximately $35-$55 per IP depending on region, block size, and reputation. RIPE and LACNIC regions are slightly cheaper; APNIC is most expensive. A /24 (256 IPs) typically costs $9,000-$14,000. Prices have softened ~15% from the 2022 peak.
Leasing ranges from $0.38 to $0.75 per IP per month depending on region and provider. IPXO, the largest marketplace, averages around $0.50/IP/month for clean RIPE blocks. Large commitments (more than 8,192 IPs) qualify for discounts down to ~$0.40/IP/month.
Depends on time horizon and capex. Under 3 years: lease. Over 5-7 years: buying breaks even and then wins on total cost. For proxy operators with stable long-run demand, buying is usually better for core fleet; leasing for burst or experimental capacity.
Yes. In the RIPE region, anyone can buy and hold IPv4 after becoming an LIR (annual fee ~€1,550). In ARIN, you need to show "needs-based" justification — essentially a usage plan for 50%+ within 24 months. APNIC and LACNIC policies vary. No region prohibits non-ISPs from owning IPv4.
RPKI (Resource Public Key Infrastructure) cryptographically verifies that a BGP announcement comes from the legitimate holder of the IP block. As of 2026, most Tier-1 transit providers drop announcements without valid ROAs. You absolutely need RPKI for both owned and leased blocks — for leased, the marketplace usually handles it.
An IP or block is "clean" if it's not listed on major spam/abuse RBLs (Spamhaus, SORBS, Barracuda, Project Honey Pot), has no history of being assigned to known abusers, and passes visual inspection of WHOIS and SWIP records. Clean blocks command a 10-20% price premium and are essential for proxy networks serving enterprise customers.
Not in the next 5-10 years. IPv6 adoption is around 45% globally in 2026 but many important services — financial, enterprise VPN, mobile app backends — are still IPv4-only. For proxy operators specifically, customer tooling is IPv4-first and target sites often reject IPv6 traffic as low-trust. IPv4 pricing should stay stable or soften gradually through 2030.
Only if you have (a) at least $100k of capex you're comfortable committing, (b) a clear multi-year product roadmap, (c) operations staff to handle abuse and RIR membership, and (d) a reason you need reputation control. Otherwise, lease through IPXO or similar and focus capex on product and acquisition.
ARIN transfers: typically 2-6 weeks including documentation, needs justification, and approval. RIPE transfers: 1-3 weeks (no needs justification). APNIC and LACNIC similar to RIPE. Leasing: minutes to hours once account and KYC are done.
For a new or mid-size proxy operator in 2026, lease your first several thousand IPs through IPXO or a similar marketplace. Preserve capex for product, engineering, and customer acquisition — which is where the real differentiation is. Move to buying for your core long-running fleet once you're 2+ years in, have predictable demand, and can handle abuse operations.
For the exceptional cases where IPv4 isn't the right substrate at all — rotating residential at scale, LTE mobile — the math is completely different and secondary-market IPv4 doesn't enter the picture.
SpyderProxy operates across all four models: owned datacenter IPs for Static DC; leased and partnered ISP blocks for Static Residential; SDK and ISP partnerships for Rotating Residential; and carrier SIM inventory for LTE Mobile. No single acquisition model is correct for a full-range proxy business.
