## Projektgeschichte und Nutzung

CIDRMerge is a C command-line tool and library for merging CIDR networks while applying whitelist-based network exclusion.

### Projektgeschichte

The SourceForge project was created in August 2005 by Daniele Depetrini. The homepage describes a CIDR merge implementation whose output is summarized as small as possible, with an optimization library, a command-line program, and conversion scripts for netmask and CIDR formats.

### Adoptionsgeschichte

The homepage says CIDRMerge has been widely used for blacklist merge and optimization and notes use by big ISPs. SourceForge file history shows releases from 1.1.0 in August 2005 through 1.5.3 in July 2008, and Homebrew still packages 1.5.3.

### Wie es verwendet wird

Users feed CIDR-formatted lines on standard input, optionally pass a whitelist file, and receive merged or whitelist-filtered CIDR output. The homepage calls out blacklist optimization, RBLDNS workflows, ACL or routing-table reduction, and network-complement computation.

### Warum Paket-Nerds sich dafür interessieren

CIDRMerge is old-school package-nerd material: a small C utility, CVS-hosted on SourceForge, still useful enough to be bottled by Homebrew years after its last upstream release. It reflects the practical sysadmin lineage of packaging compact network-list tools for spam filtering, firewalling, and route-table maintenance.
