TinyNetTool: NAT Type & Ping

TinyNetTool is a pure network diagnostic toolkit built for gamers, NAS owners, and network engineers.
(Note: This app is a diagnostic & testing utility, NOT a VPN tunnel or gaming accelerator.)

Core Features:
- Deep NAT & CGNAT Detection: Accurately identify NAT Type 1 to 4 based on RFC 3489 and detect CGNAT (100.64.0.0/10). Essential for PS5/Switch multiplayer matchmaking, P2P, and NAS port forwarding.
- NAT Optimization Guide: Step-by-step guidance on bridge mode, UPnP activation, and DMZ settings when strict NAT 3/4 or CGNAT is detected.
- Multi-Protocol Ping: Native ICMP, TCP, HTTP, and UDP modes with a live latency chart to visualize jitter and packet loss.
- Traceroute: Step-by-step hop latency display to pinpoint network routing bottlenecks.
- 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, or scan a custom range.
- Ignore Proxy Probing: Bypass system proxy settings to detect your device's real direct connection status.
- Export Markdown Diagnostics: Copy structured diagnostic logs with one tap to share on forums or GitHub.
