IPQuality is a comprehensive bash-based CLI tool for evaluating the quality and risk profile of an IP address. It performs geolocation lookups (via Maxmind and IPinfo), IP type classification (ISP, hosting, business, etc.), risk scoring from multiple threat intelligence providers (AbuseIPDB, IP2Location, IPQS, Scamalytics, etc.), streaming media unlock detection (TikTok, Disney+, Netflix, YouTube, Amazon Prime Video, Reddit, ChatGPT), email service connectivity tests (Gmail, Outlook, Yahoo, etc.), and DNS blacklist checks against 400+ databases. The script is designed for VPS owners and network administrators to quickly assess whether an IP is clean, blocked, or associated with proxies/VPNs. It supports dual-stack IPv4/IPv6, multiple operating systems, Docker, and various output formats (ANSI, JSON, plain text). The architecture is a single monolithic bash script (~78000 tokens) with modular functions, progress bars, and extensive error handling. While not a reusable library, it demonstrates advanced bash scripting patterns for network diagnostics.
