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. [Free & Pro Lifetime] - Free to download: access all tools with daily free quotas, plus rewarded video ads for extra bonus runs. - Optional Pro Lifetime Upgrade (one-time purchase, no subscription): permanently remove all ads, unlock unlimited diagnostics, and support ongoing development!
