Network Tools & IP Scanner Pro

Overview
Network Tools & IP Scanner Pro is a utility application for network diagnostics, IP analysis, DNS querying, and connection troubleshooting. The app provides a collection of diagnostic engines and network calculators designed to help users analyze local network parameters, investigate DNS records, test host connectivity, and inspect packet headers.

Key Features
- IP & Network Information: Inspect local and public IP addresses, gateway routing, subnet parameters, DNS resolver addresses, and network interface hardware specifications.
- DNS Lookup Engines: Query standard DNS records including A, AAAA, CNAME, MX, NS, TXT, SOA, PTR, SRV, and CAA. Perform reverse DNS lookups and DNS over HTTPS (DoH) queries with custom resolver selection.
- Wi-Fi & Wireless Diagnostics: View Wi-Fi link parameters, signal strength metrics, channel details, BSSID/SSID properties, and supported wireless security protocols.
- Connectivity & Port Testing: Perform ICMP ping tests, route tracing, MTU path discovery, packet loss measurement, and TCP port availability checks on target endpoints.
- Subnet & IP Calculators: Calculate IPv4 and IPv6 subnet ranges, network masks, broadcast addresses, CIDR notation, and wildcard masks.
- Packet Header Dissector: Inspect local network packet headers and examine TCP, UDP, and ICMP protocol fields with a structured hex dump viewer.
- Diagnostic History & Data Export: Save execution results to local device storage and export telemetry logs in structured JSON or CSV spreadsheet formats.
- Configuration & Preferences: Customize connection timeouts, DNS over HTTPS providers, and appearance preferences.

Who It's For
- Network administrators and system engineers managing local and remote network infrastructure.
- Software developers and IT professionals testing network services, APIs, and DNS configurations.
- Students and technology enthusiasts learning about network protocols and subnet calculations.

Permissions
- Internet (INTERNET): Used to execute network diagnostic queries, DNS lookups, and host reachability tests.
- Network State (ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE): Used to detect active connection types, interface properties, and Wi-Fi link status.
- Location (ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION): Required by the Android operating system to read local Wi-Fi SSID, BSSID, and network scan information. Location data is processed locally and is not transmitted.
- Foreground Service & VPN (FOREGROUND_SERVICE, BIND_VPN_SERVICE): Used by the local packet inspection tool to capture and dissect packet headers locally on the device.
- Notifications (POST_NOTIFICATIONS): Used to display service status while background diagnostic tasks are active.

Disclaimer
Network Tools & IP Scanner Pro is intended for diagnostic, administrative, and educational network analysis. Diagnostic outputs depend on device hardware, operating system restrictions, local network configuration, and ISP routing. This application does not bypass network security controls or grant unauthorized access to external systems.
