About This Tool

The IPv4 generator provides bulk IP address creation for developers, testers, and network engineers. It solves the need to produce long lists of IPv4 addresses for QA datasets, simulations, and system validation. Typical users supply CIDR blocks, explicit IP ranges, or a simple count; results are deterministic and repeatable for automation pipelines. When provisioning test networks, validating firewall rules, or populating config files with IPs, this tool offers precise, rule-based generation rather than random sampling.
Conceptual operation: Internally, the tool parses inputs into 32-bit IPs, expands CIDR blocks to a host range, or iterates from a start IP for a given count. It applies optional exclusions (network/broadcast) and can output in a consistent order.
Who benefits: software testers, network engineers, QA teams, and developers integrating IP lists into config files, test datasets, or simulation scenarios. Unique value lies in combining CIDR expansion, range enumeration, and count-based generation with deterministic results and simple exports.
Core features & use cases: multi-block generation, reserved-address filtering, export-ready formats, and input validation. Typical use cases include building test subnets, populating mock networks, validating IP-based rules, and generating addresses for synthetic data.

How to Use

1. Provide inputs: choose generation mode and enter a CIDR block, a start and end IP, or a count value.
2. Configure options: exclude network/broadcast addresses and select an output delimiter.
3. Run calculation: trigger the generator to produce the list.
4. Review outputs: inspect the generated IP list for size and format.
5. Export or reuse: copy to clipboard or download as CSV/JSON and feed into scripts.
