Use this free browser-based subnet split calculator from XTRAW Tools. **Subnet Split Calculator** helps you split a network into equal-sized subnets and list their addresses. Use this free browser-based calculator from XTRAW Tools to compare inputs, estimate results, and prepare useful developer output. ## How to Use the Subnet Split Calculator 1. Enter the required input shown in the form. 2. Review the network, CIDR, port, HTML, JSON, XML, CSV, YAML, delimiter, formatting, or conversion assumptions. 3. Run the tool, then copy the result or adjust one input at a time to compare scenarios. ## What This Tool Helps With Split a network into equal-sized subnets and list their addresses. It is designed for developers, IT users, site owners, ecommerce teams, SaaS teams, students, network admins, and technical users who want a fast browser-based result before relying on command-line tools, spreadsheets, scripts, parsers, production systems, or professional sources. - Network (CIDR): 192.168.0.0/24 - New Subnet Prefix: 26 /n ## Common Uses People use this calculator when they need a quick way to find CIDR ranges, network addresses, broadcast addresses, usable host ranges, wildcard masks, or subnet splits. - **Data Conversion:** Convert structured data, IP ranges, addresses, entities, CSV, JSON, XML, YAML, or related values between useful formats. - **Project Planning:** Plan networking, subnetting, data migration, web development, SaaS, hosting, or configuration workflows. - **Measurement:** Measure host counts, address ranges, port classes, subnet sizes, and other practical network or developer values. - **Developer Formatting:** Format, minify, classify, encode, decode, or prepare developer-friendly output for copy-and-paste workflows. ## Formula or Method Subnets = 2^(newPrefix − origPrefix); block size = 2^(32 − newPrefix) ## Example **Example inputs:** Network (CIDR): 192.168.0.0/24; New Subnet Prefix: 26 /n **Example result:** Using 192.168.0.0/24 split into /26, there are 4 subnets: 192.168.0.0/26, 192.168.0.64/26, 192.168.0.128/26, 192.168.0.192/26. ## Related Tools - [CIDR Range Calculator](https://xtraw.com/tools/cidr-range-calculator) - [IPv4 Range Calculator](https://xtraw.com/tools/ipv4-range-calculator) - [Wildcard Mask Calculator](https://xtraw.com/tools/wildcard-mask-calculator) - [Network Address Calculator](https://xtraw.com/tools/network-address-calculator) - [Broadcast Address Calculator](https://xtraw.com/tools/broadcast-address-calculator) - [Host Count Calculator](https://xtraw.com/tools/host-count-calculator) ## Subnet Split Calculator FAQ ### Is the Subnet Split Calculator free?
