When incidents start with "network is down", random testing wastes time. A layered checklist gives faster root-cause isolation and cleaner escalation evidence.

Core diagnostic sequence

1. Interface baseline: adapter state, IP, gateway, DNS, DHCP.
2. Local reachability: gateway ping and local path checks.
3. External reachability: public IP ping and route behavior.
4. Name resolution: DNS checks against expected resolvers.
5. Path analysis: traceroute for hop failures and latency spikes.

Why K-Network helps

K-Network packages multiple diagnostics in one Windows desktop interface so teams can run consistent first-response checks without jumping between separate tools.

Basic tests

• Ping
• Trace Route
• DNS Check
• Proxy Check

Advanced tests

• Connectivity deep check (IP config, gateways, DHCP, hosts file)
• TCP Ping for port availability
• STUN test for public IP and NAT type
• MTU test for packet-size behavior

Escalation-quality output

Use real-time logs and saved log files to attach evidence directly to helpdesk or engineering tickets. This improves handoff quality and shortens mean-time-to-resolution.

Requirements

• Windows 10/11
• .NET Framework 4.8
• Administrator rights recommended for some operations
