Net Commander

Key Features

• •Troubleshoot with Ping and Traceroute: Run single or CIDR ping and traceroute from the sidebar or terminal. Panel mode shows real-time latency charts and packet loss, with CSV export for reporting. Root-Cause Analysis Checklist provides data-driven commands for Cisco, AWS, and more.
• •Wi-Fi Analyzer and Packet Capture: Conduct quick site surveys by pulling raw Wi-Fi data from your notebook. View neighbor signals and SSIDs to detect interference, then export results to CSV or trigger a packet capture for Wireshark deep inspection.
• •IANA Port Registry Lookup: Input any TCP/UDP port or service name to instantly fetch the assigned service from the official IANA registry. Speeds up firewall audits and configuration reviews without leaving the editor.
• •CIDR Calculator with What-If Simulation: Compute IPv4 and IPv6 subnets following RFC standards. Get network address, broadcast, wildcard mask, and usable host range. The what-if simulator estimates if an address space fits a chosen block, preventing allocation mistakes.
• •SSH Profile Jumper: Save SSH connections and jump to remote servers with a few keystrokes. No more manual hostname typing or IP lookups—define profiles once and launch terminal sessions directly from VS Code.
• •Network Configuration Colorizer: Automatically apply Cisco-style syntax highlighting to .txt config files. Keywords, interfaces, IPs, and protocols are colorized for easy scanning. Private and public IPs get tooltips with ipinfo.io data for instant reference.
• •Cloud CIDRs Analyzer: Query Microsoft Azure, Amazon AWS, and Google Cloud subscriptions directly in VS Code to search for specific CIDRs in use. Avoid overlapping addresses and export results to CSV for reporting.

Use Cases

• •Cloud CIDR Overlap Check: When planning a new VPC, a DevOps engineer queries Azure, AWS, and GCP subscriptions from VS Code to see if a CIDR is already in use, preventing IP conflicts and saving hours of manual cross-referencing.
• •On-the-Fly Wi-Fi Site Survey: A network engineer walks through an office with a laptop, runs the Wi-Fi Analyzer to capture neighbor signals and SSIDs, exports the data to CSV, and identifies interference sources without leaving the editor.
• •Rapid SSH Server Access: A solution architect managing dozens of devices uses SSH Profile Jumper to instantly connect to any server. Profiles are saved once; with two keystrokes they launch a terminal session, eliminating time wasted on hostname lookups.
• •Data-Driven Root Cause Analysis: During a major outage, a network engineer uses the Root Cause Analysis Checklist for Cisco devices, following step-by-step validation commands. They produce a CSV report with ping data and logs, enabling a faster, more accurate resolution.
• •Subnet Design with What-If Simulation: Before deploying a new subnet, a designer uses the CIDR calculator's what-if simulator to test if a /24 fits within a /22 block. The tool confirms feasibility immediately, preventing costly rework during implementation.

Who is this for?

This extension is built for Network Engineers, DevOps Engineers, and Solution Architects who work with network infrastructure daily. It suits professionals managing on-premise or cloud networks (Azure, AWS, GCP) who need quick access to ping, traceroute, Wi-Fi surveys, subnet calculations, SSH connections, and root cause analysis tools within their coding environment. It also benefits system administrators and IT support staff tasked with network troubleshooting, firewall audits, and peering verification. The tool is ideal for anyone already using Visual Studio Code who wants to eliminate tab-switching between terminals, browser lookups, and external utilities.
