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 ipv4.center.

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. 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. 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.

Frequently Asked Questions

How accurate is this calculator?
The calculator provides estimates based on current market data from Q1 2026. Actual transaction prices can vary based on block cleanliness, BGP history, urgency, and negotiation. For a precise valuation, contact our sales team for a free assessment.
What is the smallest IPv4 block I can trade?
The minimum transferable and routable IPv4 block is a /24 (256 IP addresses). This is the smallest prefix accepted by most internet routing tables.
Why are RIPE blocks more expensive?
RIPE NCC covers Europe and the Middle East, regions with high IPv4 demand. Additionally, RIPE's transfer policy does not require needs-based justification (since RIPE-689), making transfers faster and simpler.
How do I get a precise valuation?
Contact ipv4.center for a free, personalized valuation of your IPv4 holdings. Our team considers all factors including blacklist status, BGP history, block type, and current market conditions.
