A /20 IPv4 block contains 4,096 IP addresses and currently costs $94,000 – $123,000 ($23 – $30 per IP) on the secondary market. Prices vary by RIR region, with RIPE NCC blocks commanding the highest premiums and AFRINIC blocks being the most affordable.
Target Audience
Regional WISPs (Wireless ISPs) and FTTH operators scaling to 1,000–5,000 subscribers, mid-tier cloud companies launching new availability zones, and hosting providers transitioning from shared to dedicated IP infrastructure.
Use Case
A /20 marks the threshold where volume discounts kick in, dropping per-IP costs from $25–$35 to $23–$30. It is the workhorse block for regional ISPs deploying FTTH (Fiber to the Home) or fixed wireless to suburban and rural communities—4,096 IPs cover thousands of subscriber CPEs with room for network management, monitoring infrastructure, and future growth. Cloud providers use /20s to bootstrap a new region or availability zone with enough addressing for virtual machines, load balancers, and NAT gateways.

Frequently Asked Questions About /20 Blocks
Everything you need to know about purchasing a /20 IPv4 block, from pricing and transfer timelines to technical requirements.
Why is the per-IP cost lower starting at /20 size?
Why is the per-IP cost lower starting at /20 size?
The /20 threshold (4,096 IPs) is where the secondary market consistently offers volume pricing. Per-IP costs drop to $23–$30, a 10–15% savings compared to /24-/21 pricing of $25–$35. This discount reflects the efficiency of transferring a single large block versus multiple smaller ones, and the reduced per-unit brokerage overhead.
Is a /20 enough for a regional ISP with FTTH deployment?
Is a /20 enough for a regional ISP with FTTH deployment?
For a regional ISP serving 1,000–5,000 subscribers, a /20 is typically sufficient. With 4,096 IPs, you can assign a public IP per subscriber CPE, reserve ranges for management (IPMI, SNMP), allocate IPs for core routing infrastructure, and still have headroom for 2–3 years of subscriber growth before needing additional space.
Should I buy a /20 or use CGNAT to conserve addresses?
Should I buy a /20 or use CGNAT to conserve addresses?
CGNAT (Carrier-Grade NAT) introduces latency, breaks end-to-end connectivity (impacting gaming, VoIP, and peer-to-peer applications), and complicates law enforcement data retention requirements. For ISPs prioritizing customer experience and regulatory compliance, purchasing a /20 and assigning public IPs is the recommended approach. CGNAT can be layered later as a supplement, not a replacement.
