Net Tools ULTIMATE

Net Tools is a practical network diagnostics toolkit for iPhone and iPad. It helps you inspect connections, troubleshoot domains, test servers, and understand what is happening on the network you are using.

The app is built for people who want clear answers without sending every diagnostic input to a remote service. Many checks run directly on device using iOS networking APIs, with plain-language results, useful timing details, and redacted export output where available.

Use Net Tools to:

- Check reachability with Ping, Trace Route, TCP Test, packet loss, jitter, IPv6, and path MTU diagnostics
- Inspect DNS records, MX records, reverse DNS, DNSSEC evidence, DNS propagation, and email security configuration
- Review HTTP status, redirects, headers, protocol negotiation, TLS certificates, SSH host keys, service banners, and WebSocket behavior
- Explore local network details with LAN scan, Bonjour, UPnP/SSDP, NTP, Wake on LAN, MAC vendor lookup, and subnet calculations
- Measure mobile-network quality, handovers, NAT64/464XLAT behavior, carrier DNS, VoIP readiness, and streaming readiness
- Use advanced utilities such as TCP/UDP terminal, DNS tampering detection, STUN/TURN/ICE testing, TLS interception checks, JWT inspection, MQTT testing, Wi-Fi QR code generation, and diagnostic report export

Net Tools keeps the interface compact and searchable, with tools grouped by category so you can get from a question to a result quickly. The terminal-inspired design stays readable, focused, and friendly to repeated use.

For responsible testing, security and pentest-style tools are bounded and designed for systems you own or have permission to test. Some network environments, iOS privacy controls, carrier limitations, and local-network permissions may affect what can be inspected.
