Buy IPv4 /23 Block
512 {ipCount} IP Addresses
Purchase a clean, blacklist-free /23 IPv4 block with 512 IP addresses. Escrow-protected transactions, managed RIR transfers, and blocks available from all five registry regions.
A /23 IPv4 block contains 512 IP addresses and currently costs $12,800 – $17,900 ($25 – $35 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
SaaS platforms that need environment isolation (production, staging, sandbox), managed service providers (MSPs) juggling multiple client networks, and digital agencies running white-label hosting for dozens of brands.
Use Case
A /23 gives you 512 addresses—enough to carve out separate subnets for production, staging, and development environments while maintaining a single aggregated BGP announcement. MSPs use it to assign /28 or /27 slices to individual clients without purchasing separate blocks for each. It is the sweet spot for organizations that have outgrown one /24 but don't yet need the four-/24 footprint of a /22.

Frequently Asked Questions About /23 Blocks
Everything you need to know about purchasing a /23 IPv4 block, from pricing and transfer timelines to technical requirements.
Why buy one /23 instead of two separate /24 blocks?
Why buy one /23 instead of two separate /24 blocks?
A contiguous /23 produces a single, cleaner BGP announcement that upstream providers prefer. Two separate /24s double your routing table footprint, increase administrative overhead, and may come from different RIR regions with mismatched transfer timelines. A /23 also simplifies reverse DNS delegation and firewall rule management.
How can I split a /23 for multi-environment use (prod, staging, dev)?
How can I split a /23 for multi-environment use (prod, staging, dev)?
You can subnet a /23 into two /24s (256 IPs each), four /25s (128 IPs each), or any CIDR combination. A common pattern is: /25 for production, /26 for staging, /27 for development, and the remainder reserved for future growth—all under one aggregated BGP announcement.
Is a /23 suitable for an MSP managing multiple clients?
Is a /23 suitable for an MSP managing multiple clients?
Yes. MSPs frequently buy a /23 and allocate /28 or /27 slices to individual clients, providing each customer with a dedicated IP range. This approach is more cost-effective than buying a separate /24 for every client and simplifies upstream routing.
What documentation do I need to transfer a /23?
What documentation do I need to transfer a /23?
Requirements vary by RIR: RIPE NCC requires a signed transfer agreement and sponsoring LIR for non-members; ARIN requires an 8.2 or 8.3 transfer request with justified need; APNIC requires a transfer agreement and resource utilization plan. ipv4.center prepares all documentation on your behalf.
