NETworkManager is a comprehensive Windows-based network administration and troubleshooting tool built with WPF and the MVVM pattern. It provides an integrated suite of network utilities including remote access (RDP, PowerShell, PuTTY, TigerVNC, WebConsole), network diagnostics (WiFi scanner, IP/port scanners, ping monitor, traceroute, DNS lookup), configuration tools (firewall, hosts file editor), and various network utilities (subnet calculator, bit calculator, OUI/port lookup, RDAP/Whois, IP geolocation). The application features a tabbed interface where each tool operates as a separate tab, profile-based configuration management for saving host/group settings, settings persistence with system-wide policy support, localization for 16+ languages, and data export capabilities (CSV, XML, JSON). The architecture follows clean separation of concerns with dedicated projects for Controls, Converters, Models, Profiles, Settings, Utilities, and ViewModels/View pairs.
SPFtoolbox is a web application for performing DNS and WHOIS lookups. It provides a user-friendly interface to query various DNS record types (A, AAAA, MX, TXT, SPF, DMARC, etc.), check blacklists, verify port connectivity, perform reverse DNS lookups, and retrieve WHOIS information. The application consists of a PHP backend that handles the lookup operations and a JavaScript frontend that manages the user interface and AJAX requests. The backend uses PHP's built-in DNS functions and integrates the phpWhois library for WHOIS queries.
