  • range2cidr

history

Project history and usage

range2cidr converts IPv4 or IPv6 address ranges into equivalent CIDR blocks and is distributed as part of IPinfo's CLI toolkit.

Project history

range2cidr is maintained as one of the standalone text and IP-range utilities in IPinfo's CLI toolkit rather than as an independent source project.

Adoption history

range2cidr is shipped through Homebrew as a standalone executable from IPinfo's broader CLI project. The same operation is also exposed as the ipinfo range2cidr subcommand.

How it is used

Users pass ranges directly or process files and standard input to produce CIDR representations. IPinfo documents it for converting start and end address columns in IP databases into CIDR form.

The conversion utility itself does not require authentication and has no documented dedicated configuration or credentials file.

Why package nerds care

range2cidr packages a common but error-prone network calculation as a composable command, useful in data pipelines, firewall preparation, routing analysis, and IP-database processing.

Timeline

  • Toolkit development: IPinfo incorporated range2cidr into its collection of standalone IP-processing binaries.
  • Current usage: The utility is available both as range2cidr and through the ipinfo range2cidr command route.
