🔬Technical Introduction
Core ConceptIPv4 range expansion involves converting network ranges, CIDR notation, or subnet ranges into individual IP addresses. This process is essential for network administration, security scanning, and IP address management, allowing administrators to see all addresses within a given range.
Best PracticesAlways validate input ranges before expansion. Be mindful of large ranges that may generate thousands of addresses. Use appropriate output formats for your specific use case. Consider network boundaries and avoid expanding ranges that cross subnet boundaries unnecessarily.
