IPv4 Subnet Value Calculator
Estimate the current market value of any IPv4 subnet based on block size and RIR region. Powered by real marketplace data from IPv4Center.com.
How IPv4 Subnet Values Are Calculated
IPv4 address values depend on several factors including subnet size, RIR region, cleanliness (blacklist status), BGP routing history, and current market supply and demand. Larger blocks offer lower per-IP pricing due to economies of scale, while RIPE NCC blocks typically command premium prices due to high demand in Europe and the Middle East.

Factors That Affect IPv4 Pricing
Understanding these factors helps you make informed buying and selling decisions.
Subnet Size
Larger blocks (/16, /17) have lower per-IP costs than smaller blocks (/24). Buyers of larger blocks benefit from volume pricing.
RIR Region
RIPE NCC blocks command 10-15% premium over other regions. AFRINIC blocks are typically the most affordable.
Blacklist Status
Clean blocks with no blacklist entries are worth more. Run a blacklist check to verify. Blocks with active blacklistings may be discounted 10-20%.
BGP History
Blocks with clean routing history and no hijack incidents command better prices than those with problematic BGP records.
Market Timing
IPv4 prices have grown 8-12% annually since exhaustion. Track trends with our price tracker. Seasonal demand and economic conditions also affect pricing.
Block Type
Legacy allocations, Provider Independent (PI) space, and Provider Aggregatable (PA) space may have different transfer requirements affecting value.
Understanding IPv4 Address Market Pricing
The IPv4 address market operates as a secondary transfer market where pricing is determined by block size, RIR region, IP reputation, and current supply-demand dynamics. As of Q2 2026, /24 blocks (256 addresses) trade between $35-52 per IP address depending on region and cleanliness, while larger /16 blocks (65,536 addresses) command $28-42 per IP due to volume efficiencies.
RIPE NCC region blocks carry a 10-15% premium over other regions because of sustained demand from European cloud providers, hosting companies, and enterprises. ARIN blocks trade at market average due to balanced supply and demand, while APNIC blocks have seen price increases of 12% year-over-year driven by Asian market expansion. AFRINIC blocks remain the most affordable but carry additional transfer complexity.
Market pricing is also influenced by RIR transfer policies — RIPE NCC's policy (RIPE-689) does not require needs-based justification for transfers, making transactions faster (typically 5-10 business days). ARIN requires a needs assessment under its Specified Transfer Listing Service (STLS), which can extend timelines to 4-8 weeks and limits the buyer pool to organizations that can demonstrate operational need.
IPv4 Block Size Impact on Value
Block size is the single largest determinant of per-IP pricing in the IPv4 market. A /24 (256 IPs) is the minimum globally routable prefix — most ISPs and transit providers filter announcements smaller than /24 from their BGP tables. This makes /24 the smallest independently usable block and establishes the floor unit for trading.
Larger blocks command lower per-IP prices due to economies of scale in transaction costs and operational simplicity. A /20 block (4,096 IPs) typically trades at 15-20% less per IP than equivalent /24 blocks, while a /16 (65,536 IPs) may trade at 25-35% less per IP. However, the total transaction value increases substantially — a /16 at $30/IP represents a $1.97 million transaction versus $13,300 for a single /24 at $52/IP.
Clean routing history and absence of blacklist entries can add 5-15% premium to block pricing regardless of size. Blocks with verified clean BGP history (no hijacking incidents, stable origin AS) and zero blacklist detections across all major DNSBLs are classified as "premium clean" inventory. Conversely, blocks with active blacklist entries or recent abuse history may be discounted 10-25% below market average.
