👤 WHO IT'S FOR

👨‍💻 Network admins checking host reachability and latency

🛠️ Developers verifying DNS, HTTP endpoints, and TLS certs

⚡ Power users who want a serious analyzer — not a cluttered multi-tool

——————————————

🌐 CORE DIAGNOSTICS

🏓 Ping test — high-precision ICMP with live latency graphs (IPv4/IPv6 where supported)

🧪 HTTP / API tester — GET, POST with headers and status codes

🔐 DNS query — advanced lookups for A, AAAA, CNAME and more

🔎 Port scan — common ports for exposure checks

🔒 TLS / SSL inspect — certificate and handshake details

🗺️ IP & Whois — geolocation and registration details

🛤️ Traceroute — hop-by-hop TTL ping (falls back to DNS resolve if ping -t is unavailable)

🏠 LAN Scan — find devices on your Wi‑Fi subnet (no MAC on Android 10+)

✨ WHY NET ANALYZER

🆓 Ad-free and lightweight — no upsell walls in the critical path

🔓 No account required to diagnose

🔒 Privacy-minded — use the tools you need on device

⚡ Built for troubleshooting first — deep ping, HTTP, DNS, and port flows

📋 NOTE

ICMP, port scan, and DNS behavior can vary by carrier, VPN, and Android version. Results reflect what the device stack reports.

💡 TYPICAL TROUBLESHOOTING

• Is the server down for everyone or just me? Ping it, then run an HTTP check on the same host.

• Laggy games or calls: watch the live latency graph for jitter and packet loss.

• Just changed DNS records? Query A, AAAA, CNAME, MX and TXT to confirm what resolvers return.

• Certificate warnings: inspect the TLS issuer, validity dates and handshake.

• API debugging: send GET or POST with custom headers and read status codes and response time.

• Exposure check: scan common ports on your own server or router.
