Network tools for ping, DNS, IP analysis, and connectivity tests.
NetTools is a practical network utility toolkit for system administrators, developers, network engineers, IT professionals, students, and anyone who needs quick network diagnostics from an Android device. SUBNET & CIDR CALCULATOR * Network and broadcast addresses * Usable host ranges * Total addresses and usable hosts * Subnet and wildcard masks * Dotted-decimal and binary representations * Visual network and host bit allocation * Prefix support from /0 to /32 * Support for /31 point-to-point networks and /32 single-host addresses PING & LATENCY TEST Check network reachability and measure response times. * Test hostnames, IPv4, and IPv6 targets * Configurable packet count * Configurable timeout * Minimum, average, and maximum latency * Packet loss percentage * Individual ping attempt results DNS LOOKUP Inspect commonly used DNS record types. * A * AAAA * CNAME * MX * NS * TXT TCP PORT CHECK Check TCP connectivity for a specific host and port. * Test individual TCP endpoints * Open, connection-refused, and timeout results * Common port presets * SSH, DNS, HTTP, HTTPS, MySQL, and other frequently used ports Port testing is intentionally limited to user-specified individual targets and is designed for focused connectivity diagnostics rather than mass scanning. HTTP / HTTPS TEST Check web endpoint connectivity and inspect response information. * HTTP status codes * Response messages * Redirect paths * Connection latency * TLS information where available * Server response headers * Content type and other response metadata IP INFORMATION Understand and classify IPv4 addresses. * Private addresses (RFC 1918) * Public addresses * CGNAT addresses (RFC 6598) * Loopback addresses * Link-local addresses * Multicast addresses * Binary and hexadecimal representations * 32-bit integer representation * Optional public IP lookup IP CONVERTER Convert IPv4 addresses between multiple formats without requiring network access. * Dotted decimal * 32-bit integer * Hexadecimal * Binary * Octal URL ANALYZER Parse URL and URI components directly on your device. * Scheme * Host * Port * Path * Query parameters * Fragments * Decoded key-value parameters DEVICE NETWORK INFORMATION View available network and interface information provided by Android. * Wi-Fi, cellular, Ethernet, and VPN status * Local IPv4 and IPv6 addresses * Default gateway information * Configured DNS resolvers * Network interface details * Interface names, MTU, and link status The app also provides explanations around Android's handling of network identifiers and privacy-related restrictions. HISTORY & FAVORITES Keep your frequently used diagnostics organized. * Save previous test results locally * Search diagnostic history * Filter results by utility type * Clear history when needed * Save frequently tested servers, subnets, and URLs * Quickly run saved favorites again * Share diagnostic results using Android's standard share options DESIGNED FOR PRACTICAL NETWORKING NetTools is built around commonly needed networking utilities in a straightforward Android interface. * No account required for core functionality * Material 3 interface * Light Mode, Dark Mode, and System Default themes * Focused network-related permissions * No location permission required for the core tools Some features, such as DNS queries, ping tests, HTTP/HTTPS testing, and public IP lookup, naturally require network connectivity. IMPORTANT USE INFORMATION NetTools is intended for legitimate network troubleshooting, administration, development, education, and testing on systems and networks you own or are authorized to test. The app does not perform mass port scanning or automated network discovery. Users are responsible for ensuring that their use of network diagnostic tools complies with applicable laws, policies, and authorization requirements.
