/23 IPv4 Block FAQ
Frequently asked questions about buying a /23 IPv4 subnet
What is a /23 IPv4 block?
What is a /23 IPv4 block?
A /23 IPv4 block contains 512 IP addresses (two contiguous /24 blocks). It is commonly used by small ISPs, hosting companies, and organizations that need more address space than a single /24 but don't yet require a larger allocation. A /23 provides a good balance between cost and capacity.
How much does a /23 IPv4 block cost?
How much does a /23 IPv4 block cost?
A /23 IPv4 block (512 IPs) typically costs between $12,800 and $17,900 depending on RIR region and market conditions. The per-IP cost ranges from $25 to $35, with pricing similar to individual /24 blocks as both fall within the same pricing tier.
What are the advantages of buying a /23 over two /24 blocks?
What are the advantages of buying a /23 over two /24 blocks?
Buying a single /23 instead of two /24 blocks offers several advantages: a single BGP announcement instead of two (reducing routing table pressure), potentially lower per-IP cost through volume pricing, simpler IP address management, and the ability to aggregate the prefix for more efficient routing.
