Pay once, own forever. No subscription. No ads. TinyNetTool is a pure network diagnostic tool built for gamers, NAS owners, and network engineers.

Core Features:

• Deep NAT & CGNAT Detection: Identify NAT Type 1 to 4 based on RFC 3489 and detect CGNAT (100.64.0.0/10).
• Export Markdown Diagnostics: Copy structured diagnostic logs with one tap.
• Multi-Protocol Ping: ICMP (native), TCP, HTTP, and UDP modes with a live latency chart to visualize jitter.
• DNS Lookup: Query A/AAAA/CNAME/MX/NS/TXT records directly against public resolvers.
• TCP Port Scanner: Scan common NAS and remote desktop ports in one tap.
• Ignore Proxy Probing: Bypass system proxy settings to detect real direct connection status.
• Traceroute: Step-by-step display of every hop your packets travel.
