Understanding IPv4 Block Pricing by Size
As IPv4 addresses become scarcer, pricing has shifted from simple allocation costs to a market-driven structure based on block size, demand, and usability. Not all IPv4 blocks are priced the same. A /24, /23, and /22 each offer different advantages, limitations, and cost profiles. Understanding the pricing breakdown between these block sizes helps buyers choose the most efficient and cost-effective option for their network needs.
IPv4 pricing is no longer just about how many addresses you get, but how those addresses can be used.
What IPv4 Block Sizes Really Mean
IPv4 block sizes are defined by prefix length, which determines how many usable IP addresses are included.
- A /24 block contains 256 total addresses, typically 254 usable
- A /23 block contains 512 total addresses, typically 510 usable
- A /22 block contains 1,024 total addresses, typically 1,022 usable
While larger blocks provide more addresses, pricing is not always linear. Market behavior, routing policies, and reputation considerations all influence cost.
Why /24 Blocks Often Cost More Per IP
On a per-address basis, /24 blocks are usually the most expensive. This is because /24 is the smallest block size that can be independently routed on the global internet.
Many networks, providers, and security systems require at least a /24 prefix for BGP announcements. As a result, /24 blocks are highly liquid and in constant demand, especially for hosting providers, VPN services, and regional deployments.
This demand drives up per-IP pricing, even though the total block cost is lower than larger prefixes.
/23 Blocks: A Balance Between Size and Flexibility
A /23 block offers double the addresses of a /24, but it introduces some tradeoffs. While a /23 can be routed as a single prefix, it can also be split into two /24s for flexibility.
This split capability makes /23 blocks attractive for buyers who want scalability without committing to a much larger block. However, not all networks accept split announcements equally, and this can affect routing strategy.
Pricing for /23 blocks often sits between /24 and /22 blocks on a per-IP basis, reflecting both flexibility and moderate demand.
/22 Blocks and Economies of Scale
/22 blocks provide a larger pool of addresses and typically offer the lowest price per IP. Buyers seeking volume, such as cloud providers, CDNs, or large enterprises, often prefer /22 blocks for long-term growth.
However, larger blocks require more planning. Routing, segmentation, reverse DNS, and reputation management become more complex as block size increases. Not all buyers are equipped to manage these operational requirements.
Lower per-IP pricing makes /22 blocks attractive, but only when the buyer can effectively use the entire address space.
Market Demand and Liquidity Differences
Liquidity plays a major role in IPv4 pricing. /24 blocks are easier to resell or reassign because they fit common routing and deployment models. This liquidity supports higher prices.
Larger blocks may take longer to sell or lease, especially if buyers only need a small number of addresses. This reduced liquidity often results in discounted pricing for /22 blocks compared to smaller prefixes.
Reputation and History Impact Pricing
IPv4 pricing is not determined by block size alone. Address reputation matters. Clean blocks with no history of abuse, spam, or blacklisting command higher prices regardless of size.
A /24 with a strong reputation may be worth more than a /22 with unresolved abuse issues. Buyers factor reputation into pricing because remediation costs can be high.
Leasing vs Buying and Its Effect on Cost
Pricing also varies depending on whether IPv4 blocks are leased or purchased. Leasing spreads cost over time and can make larger blocks more accessible. Buying requires higher upfront investment but provides long-term control.
Block size influences leasing rates as well. Smaller blocks often lease faster, while larger blocks may offer better long-term value.
How IPv4Hub Helps Navigate IPv4 Pricing Decisions
ipv4hub.net helps businesses evaluate IPv4 block pricing by providing access to verified address holders and transparent market options. IPv4Hub follows regional internet registry policies and supports both leasing and transfer transactions.
By offering clean, compliant IPv4 blocks in multiple sizes, IPv4Hub allows buyers to compare /24, /23, and /22 options based on real-world needs, budget, and growth plans. This guidance helps organizations avoid overpaying or selecting blocks that do not fit their operational model.
Choosing the Right Block Size for Your Network
There is no single “best” IPv4 block size. The right choice depends on routing requirements, scalability plans, budget constraints, and technical capacity.
Smaller organizations may prioritize /24 blocks for flexibility and ease of deployment. Growing businesses may choose /23 blocks to balance cost and expansion. Large operators often benefit most from /22 blocks due to lower per-IP pricing.
Avoiding Common Pricing Mistakes
One common mistake is focusing only on per-IP cost. Operational complexity, routing acceptance, and reputation risks can outweigh initial savings.
Another mistake is buying more addresses than needed without a clear utilization plan. Unused address space still requires management and compliance.
Long-Term Pricing Trends for IPv4 Blocks
As IPv4 scarcity continues, prices across all block sizes are expected to rise. However, demand patterns will continue to favor routable, flexible blocks.
Understanding these dynamics allows buyers to make informed decisions rather than reactive purchases.
IPv4 Block Pricing
Pricing differences between /24, /23, and /22 IPv4 blocks reflect more than just address counts. Demand, routing flexibility, reputation, and market liquidity all play a role.
By understanding how these factors influence cost and working with trusted platforms, businesses can secure IPv4 resources that align with both current needs and long-term strategy in a competitive address market.
