mapCIDR is a Go utility for performing multiple operations on subnet/CIDR ranges, such as expansion, slicing, aggregation, filtering, sorting, and IP format conversion. It works both as a standalone CLI tool and as a Go library, and is designed to ease load distribution for mass scanning operations.
Use cases
- expand a CIDR range into a list of individual IPs
- split a large subnet into smaller CIDR blocks for distributed scanning
- aggregate a list of IPs and CIDRs into minimal subnets
- count the number of hosts in a CIDR range
- filter IPv4 or IPv6 addresses from mixed input
- convert IPs between IPv4 and IPv6 formats
- shuffle IP and port lists for scanning
When to choose
- you need fast command-line manipulation of CIDR ranges and IP lists
- you are distributing mass scanning workloads across chunks of a network
- you want a Go library for CIDR math in your own tooling
When to avoid
- you need interactive subnet planning with a GUI
- your task is general-purpose network scanning rather than CIDR manipulation
