How IPv4 Hub Helps You Choose the Right IP Block Size
Selecting the right IPv4 block size is one of the most important decisions businesses must make when building or expanding their online infrastructure. Whether you run a hosting platform, VPN service, SaaS product, or enterprise network, your IP block directly affects routing, performance, scalability, and budget. However, many organizations struggle to determine whether they need a /24, /23, /22, or even larger block, and misunderstandings can lead to unnecessary costs or operational limitations.
IPv4 Hub simplifies this process by guiding clients through each step to ensure they choose the block size that best matches their technical and business requirements. This article explains how IP block sizing works and the ways IPv4 Hub helps businesses select the right range.
Understanding IPv4 Block Sizes
IP block sizes are expressed using CIDR notation, which indicates how many addresses are included in a subnet. Common leasing options include:
- /24 – 256 IPs
- /23 – 512 IPs
- /22 – 1,024 IPs
- /21 – 2,048 IPs
The smaller the number after the slash, the larger the block.
Each block size serves different use cases depending on traffic demand, routing requirements, growth expectations, and operational scale.
Common Factors That Influence Block Size Selection
To determine the right IPv4 block, several factors need to be evaluated carefully.
1. Your Current Usage and Traffic Needs
Businesses with modest requirements may only need a /24, while large-scale providers may require thousands of IPs.
2. Routing or BGP Requirements
Most networks need at least a /24 to announce via BGP. Smaller ranges (/25, /26) may not be accepted by many upstream providers.
3. Email Reputation and Deliverability
Larger blocks allow for segmentation, reputation isolation, and more flexibility for outbound mail services.
4. Scalability and Growth Planning
Choosing a block too small can lead to fragmentation later, while a block too large increases unnecessary costs.
5. Budget Constraints
IP pricing increases significantly for cleaner, larger blocks. A right-size approach prevents overspending.
IPv4 Hub helps clients evaluate each of these considerations.
How IPv4 Hub Helps You Select the Right Block Size
1. Needs-Based Assessment
IPv4 Hub starts with a conversation to understand:
- Your infrastructure
- Your expected growth
- Your routing environment
- The type of services you operate
This ensures the recommended block aligns with real operational needs.
2. Expert Guidance on Routing and BGP
Because not all block sizes route equally, IPv4 Hub assists clients with:
- Understanding the minimum acceptable BGP announcement size
- Determining aggregation possibilities
- Designing routing policies
This prevents routing issues or upstream provider rejections.
3. Clean IP Availability Options
IPv4 Hub offers a range of clean, reputation-verified blocks. If a desired size is unavailable, they explain alternative options and the pros and cons of each size.
4. Future-Proof Planning
Block recommendations include guidance for:
- Anticipated expansion
- Avoiding fragmentation
- Minimizing price increases over time
This is especially valuable for high-growth companies.
5. Transparent Pricing Comparisons
Clients receive clear comparisons of pricing for /24, /23, /22, and other block sizes—helping them match their budget with the most suitable range.
Why Choosing the Right Block Size Matters
Selecting the wrong block size can lead to:
- Routing problems
- Overlapping infrastructure
- Poor IP reputation management
- Wasted budget
- Difficulty scaling
IPv4 Hub ensures clients avoid these pitfalls through informed, expert-driven recommendations.
