Welcome to Nadzoring’s Documentation!

Nadzoring (from Russian “надзор” — supervision/oversight + English “-ing” suffix) is a free and open-source command-line tool for detecting website blocks, monitoring service availability, and network analysis. It helps you investigate network connectivity issues, check if websites are accessible, analyze network configurations with comprehensive DNS diagnostics — including reverse DNS, DNS poisoning detection, ARP spoofing monitoring, SSL/TLS certificate analysis, HTTP security header auditing, email security validation (SPF/DKIM/DMARC), subdomain discovery, and much more.

pip install nadzoring
nadzoring --help

Key Features

  • DNS Analysis — resolve, trace, compare, health-check, benchmark DNS servers

  • Reverse DNS — PTR record lookups for IPv4 and IPv6

  • DNS Poisoning Detection — detect censorship, CDN routing, or manipulation

  • Network Diagnostics — ping, traceroute, port scanning, HTTP probing, WHOIS, comprehensive domain information

  • Security Auditing — SSL/TLS certificate inspection, HTTP security headers, SPF/DKIM/DMARC validation, subdomain discovery, continuous certificate monitoring

  • ARP Security — cache inspection, spoofing detection, real-time monitoring

  • Multiple Output Formats — table, json, csv, html, html_table

  • Cross-Platform — Linux, Windows, macOS
