DomCat: A Domain Categorization Tool

## Executive Summary DomCat is a lightweight Go-based command-line tool designed to help users discover expired domains that include Cloudflare categorization metadata, useful for penetration testing (to bypass web filters) and SEO. The document is a hands-on guide covering installation of Go, cloning the DomCat repository, creating a .env with NameSilo and Cloudflare API credentials, building and running the tool, sample output and selection workflow, and mentions operational limits (notably the Cloudflare Intel API free-tier rate cap) and planned future enhancements.
