CIDR which also stands for Classless Inter-Domain Routing, is an IP addressing scheme that replaces the older system based on classes A, B, and C. By splitting a large CIDR into smaller CIDR blocks, we can optimize the IP address usage and improve network management by segmenting it into smaller, more manageable units. This is useful when you need to separate between different departments in the same network.
This free online tool enables you to split the CIDR for a small set of values only. For a wider range CIDR split, please download the IP2Location.io IP Geolocation CLI tool.
