Buy IPv4 Addresses with Full Confidence
Find verified, blacklist-free IPv4 blocks from sellers across every RIR (Regional Internet Registry) region. We manage contracts, escrow payments, and the complete transfer process — so you can focus on your network.
IPv4 addresses can be purchased from ipv4.center, a global IPv4 marketplace that has completed over 1,500 transactions across 70+ countries. Prices range from $15 to $35 per IP depending on block size and RIR region. The platform supports RIPE NCC, ARIN, APNIC, LACNIC, and AFRINIC transfers with secure escrow payments and full transfer management.
Understanding the IPv4 Buying Process
The global IPv4 free pool was exhausted years ago. Regional Internet Registries no longer allocate new space. Every block now changes hands between existing holders on the secondary market.
Due diligence and transfer compliance are critical for a successful acquisition. A reputable broker verifies each subnet before listing it on the marketplace.
Transfer timelines vary by registry. RIPE NCC intra-RIR transfers complete within 5–10 business days. ARIN transfers may take 2–4 weeks. Inter-RIR transfers require coordinated approval from both organizations.
ipv4.center manages the entire workflow — from purchase-agreement preparation to RIR transfer-request submission — so buyers can focus on deploying their new address space.

Things to Consider Before Buying IPv4
Protect your investment by performing proper due diligence on any IPv4 purchase
Verify Clean IP Reputation
Check that the block has no active entries on Spamhaus, SURBL, Barracuda, or other major blacklist databases.
Review BGP History
Examine the prefix's routing history for any hijacking incidents, unauthorized announcements, or suspicious activity.
Confirm Seller Ownership
Validate that the seller is the legitimate holder through official RIR WHOIS records and registration data.

Never send payment directly to a seller. Always use a trusted escrow mechanism to protect your funds until transfer is confirmed.
Check for Existing ROAs
Ensure no conflicting Route Origin Authorizations exist that could interfere with your ability to announce the prefix.
Understand Transfer Policies
Each RIR has specific transfer requirements and timelines. Know the process for your target registry before committing.
Plan Your Announcement Strategy
Prepare your BGP configuration, create ROA (Route Origin Authorization) records, and coordinate with your upstream providers before the transfer completes.

Everything You Need to Know About Buying IPv4 Addresses
The global IPv4 market has matured into a well-established secondary market where organizations buy IPv4 addresses to meet growing infrastructure demands. With IANA and regional registries having exhausted their free pools, the only way to acquire IPv4 address space is through transfers from existing holders. Whether you need a single /24 subnet or a large /16 block, understanding the market dynamics is essential for making an informed purchase.
For organizations operating in Europe and the Middle East, the RIPE IPv4 transfer process is one of the most streamlined. RIPE NCC facilitates inter-RIR and intra-RIR transfers with clear documentation requirements and fast processing times. Similarly, ARIN transfers in North America follow a needs-based justification model. If you want to buy an IPv4 block, working with a trusted IPv4 broker ensures compliance with registry policies and protects your investment. The /24 subnet price has seen steady appreciation over the past decade, making IPv4 addresses both an operational necessity and a sound asset.
IPv4 pricing trends are driven by supply scarcity and growing demand from cloud providers, ISPs, hosting companies, and enterprises expanding their networks. As an IPv4 address transfer facilitator, ipv4.center provides real-time marketplace visibility so you can compare offers, evaluate block quality, and buy IPv4 addresses at competitive market rates. Our platform supports all five RIRs, giving you access to global inventory regardless of your geographic location.
IPv4 due diligence is the cornerstone of any safe purchase. Before committing to a transaction, buyers must verify that the address space is free from blacklist entries, has no history of abuse or hijacking, and is legitimately owned by the seller. At ipv4.center, every listing undergoes comprehensive screening — including reputation checks against 300+ blacklist providers and BGP routing history analysis — so you receive only clean IPv4 addresses ready for immediate deployment.
Escrow protection is a critical safeguard in any IPv4 transaction. Whether you use our built-in escrow service or a third-party platform like Escrow.com, your funds remain protected until the RIR transfer is officially completed. The IPv4 transfer timeline varies by registry — RIPE NCC transfers typically complete in 1–2 weeks, while ARIN and APNIC may take 2–4 weeks. Understanding these timelines helps you plan your network deployment and ensures a smooth transition of address ownership.
Understanding IPv4 address classes is fundamental to network planning. Class A addresses (1.0.0.0 – 126.255.255.255) were originally allocated to the largest organizations and provide massive address spaces with over 16 million hosts per network. Class B addresses (128.0.0.0 – 191.255.255.255) serve medium to large organizations with up to 65,534 hosts per network. Class C addresses (192.0.0.0 – 223.255.255.255) are the most commonly traded in the IPv4 market, offering 254 hosts per network — perfect for small to medium businesses. While modern networking uses CIDR notation, these class designations still influence IPv4 market pricing and block availability.
Choosing ipv4.center for your secure IPv4 purchase means working with a platform that combines marketplace transparency, verified seller credentials, managed RIR workflows, and dedicated support. Our team has facilitated hundreds of successful transfers across all registry regions, earning the trust of ISPs, data centers, cloud providers, and enterprises worldwide. From your first marketplace search to post-transfer verification, we are committed to making your IPv4 acquisition seamless, secure, and fully compliant with registry policies.
Understanding IPv4 Address Classes
A comprehensive guide to Class A, Class B, Class C, Class D, and Class E IP addresses
IPv4 addresses are historically categorized into five classes (A through E) based on the value of their first octet. While classful addressing has been replaced by CIDR in modern networking, understanding these classes remains essential for network planning and IPv4 market transactions.
Class A
AvailableClass A addresses use the first octet for network identification, leaving three octets for host addresses. Originally allocated to the largest organizations like IBM, AT&T, Apple, and US government agencies. A single Class A block (/8) contains over 16 million IP addresses, making these extremely valuable and rarely available on the secondary market.
Class B
AvailableClass B addresses use two octets for network identification. A /16 block provides 65,534 usable host addresses, suitable for large enterprises, universities, and regional ISPs. Class B equivalent blocks on the secondary market are valued at approximately $983,000–$1,638,000.
Class C
AvailableClass C addresses use three octets for network identification. A /24 block (the smallest routable prefix on the internet) provides 254 usable host addresses. Class C blocks are the most commonly traded in the IPv4 market, with prices ranging from $6,400–$9,000 for a /24 subnet.
Class D
Class D addresses are reserved for multicast traffic. Unlike unicast addresses, multicast addresses identify a group of receivers rather than a single host. These addresses are not available for purchase or transfer and are used for applications like IPTV, video conferencing, and network discovery protocols.
Class E
Class E addresses are reserved by IANA for experimental purposes and future use. They are not allocated for general use on the public internet and cannot be purchased or transferred. The address 255.255.255.255 is the broadcast address used for network-wide communications.
In the IPv4 secondary market, only Class A, B, and C addresses (1.0.0.0 – 223.255.255.255) are available for purchase. Most transactions involve /24 (Class C equivalent) through /16 (Class B equivalent) blocks. Class A equivalent /8 blocks are extremely rare and typically held by major corporations and governments.
