About the 158.x.x.x/23 IPv4 Block

The IPv4 block 158.x.x.x/23 represents a compact and efficient subnet commonly used by organizations that need a dedicated address range without the overhead of large allocations. A /23 provides 512 IPv4 addresses, making it ideal for hosting companies, data centers, SaaS providers, and enterprises expanding their network infrastructure in a controlled way.  Learn the reason of IPv4 Shortage and What to Do.

This block size is often preferred by companies looking for the right balance between scalability and operational efficiency. It offers enough space for routing, virtual machines, VPNs, servers, and internal services while keeping management simple and cost-effective.

Why a /23 Block Is Valuable

A /23 block is large enough to support growing networks but small enough to avoid the higher acquisition costs and management requirements of /22 or /21 ranges. Many organizations choose /23 blocks because they fit well into:

• Dedicated hosting environments

• Cloud workloads

• VPN gateways

• Multi-region server deployments

• Corporate networks that need new public address segments

Because demand for IPv4 space continues to rise globally leads to shortage of IPv4, /23 ranges have become a practical choice for businesses wanting guaranteed address availability without exceeding their required capacity. Learn Top Use Cases for a /23 IPv4 Block in Modern IT Environments

Typical Use Cases for 158.x.x.x/23

A /23 block can support a wide variety of use cases. The most common include:

Hosting and Cloud Deployments

Providers often allocate /23 blocks to customer environments, containers, Kubernetes clusters, or virtual machines where predictable addressing is needed.

Load Balancing and Application Scaling

A /23 allows teams to separate production, staging, and testing environments under the same routed range. Learn in detail, How /23 Subnets Support Load Balancing and Application Scaling

Network Expansion

Organizations expanding across regions or adding services often request /23 blocks because they provide enough space for multiple subnets or dedicated teams.

Managed Services

IT service providers use /23 ranges as part of managed security, monitoring, and dedicated IP solutions.

ARIN and Regional Assignment Details

The 158.x.x.x range is historically tied to ARIN-managed territories. Organizations that obtain space under ARIN benefit from strong documentation processes, transparent ownership validation, and well-maintained WHOIS records. Maintaining accurate registry data is essential for routing, compliance, and preventing disputes during transfers. Understand ARIN IPv4 Transfer Process in detail. 

Importance of a Clean and Verified Range

For businesses depending on email deliverability, advertising networks, or reputation-sensitive applications, it is crucial to ensure the 158.x.x.x/23 block is free from prior abuse, blacklist entries, or misconfigurations. Clean IP space ensures smooth performance, prevents traffic issues, and protects a company’s digital reputation. Read the Role of Blacklist Checks in Safe IPv4 Leasing.

This is why verified brokers, compliance checks, and pre-transfer audits matter. A clean IP block saves time, reduces operational friction, and supports long-term reliability. Understand how to buy IPv4 Address safely from trusted brokers.
