Finding available IPv4 address space has become one of the biggest challenges for hosting companies, data centers, VPN providers, SaaS platforms, and network operators. With IPv4 exhaustion officially recognized worldwide, the supply is limited, the demand keeps rising, and organizations must navigate a competitive market to secure clean, verifiable IP blocks.
This guide explains how to locate available IPv4 space, what to check before purchasing, and why working with a trusted broker is essential for safe transactions.
Why Finding Available IPv4 Space Is Difficult
IPv4 scarcity is the primary reason the search is complex. Regional Internet Registries (RIRs) such as ARIN, RIPE, APNIC, LACNIC, and AFRINIC have either completely depleted their IPv4 pools or have strict waiting-list systems. That means companies must rely on the secondary market—private sellers, leasing platforms, and brokerage services—to obtain usable IPv4 blocks.
Additionally:
- Clean IPs are harder to find
- Prices fluctuate month to month.
- Competition for blocks /24, /23, and /22 is intense.
- Fraud and impersonation risks are higher in unregulated markets
Because of these challenges, businesses need a clear strategy to search safely and efficiently.
Best Ways to Find Available IPv4 Address Space
Below are the most reliable methods for locating legitimate, ready-to-transfer IPv4 ranges.
1. Work with a Trusted IPv4 Broker
The safest and fastest method is to partner with a verified IPv4 broker. Brokers maintain networks of sellers with pre-approved and clean IPv4 ranges, reducing downtime and administrative complexity.
They also handle RIR compliance, transfer documentation, escrow, pricing guidance, and fraud prevention.
2. Search Through IPv4 Marketplaces
Several global marketplaces allow buyers to browse available /24–/16 blocks. These platforms usually show:
- Available prefix sizes
- Price per IP
- RIR region
- Transfer eligibility
However, many listings are outdated or from unverified sellers, so marketplace searching should be paired with broker verification.
3. Explore Leasing Platforms
If you don’t need permanent ownership, leasing IPv4 is often:
- Faster
- Cheaper upfront
- Easier for short-term scaling
Leasing platforms maintain pools of ready-to-assign IPs that can be used for hosting, VPN, SaaS, scraping, or enterprise expansion.
4. ARIN & RIPE Transfer Logs
Some organizations publish voluntary transfer logs that reveal which companies are actively transacting IPv4 space. While not a source of direct sales, these logs help identify active sellers and market trends.
5. Contact Network Operators Directly
Large enterprises, ISPs, and hosting companies often hold unused or legacy IP space. Some are willing to sell allocations after internal audits. This method requires more time and negotiation but can result in competitive pricing.
Checklist Before Buying IPv4 Space
Never purchase an IPv4 block without verifying the following:
Ownership / WHOIS Validity
Confirm the block belongs to the seller and is not hijacked.
RIR Transfer Eligibility
Some blocks cannot be transferred across regions or have pending disputes.
Blacklist Status
Check RBLs for spam, malware, or historical abuse.
Geolocation Accuracy
Incorrect location mapping can cause service disruptions.
Routing History
Confirm the block has not been involved in hijacking or suspicious BGP activity.
Price Evaluation
Compare current market averages to avoid overpriced blocks.
These checks protect you from fraud, failed transfers, and unusable IP ranges.
