What can this network analysis tool check in the browser?

It can run real DNS-over-HTTPS lookups, show your current public IP address, geolocate public IPs, resolve A and AAAA answers, run browser-side reachability probes, calculate subnets and CIDR ranges, and parse packet snippets or network logs pasted into the page.

Who should use the Network Analysis Workbench?

It is designed for network engineers, sysadmins, SOC analysts, NOC teams, DevOps teams, IT support teams, students studying networking, and site owners who need quick browser-based diagnostics with clear next steps.

Can I use this workbench for DNS and IP troubleshooting?

Yes. It is especially useful for DNS and IP troubleshooting because it lets you inspect public A, AAAA, MX, TXT, NS, and CNAME answers, identify resolved edge IPs, geolocate public addresses, compare your own public IP context, and review packet or log snippets in the same place.

Can this page do real ping, traceroute, TCP port scanning, or TLS certificate inspection?

No. A frontend-only browser page cannot perform raw ICMP ping, hop-by-hop traceroute, TCP socket scans, or arbitrary TLS certificate inspection. This workbench keeps only the real checks the browser can honestly perform and links you to related network tools for the broader suite.

Is this network analysis tool free to use?

Yes. The Network Analysis Workbench is free to use, runs in the browser, and is designed for fast diagnostics without sign-up, installation, or extra software.

Network Analysis

Full browser workbench for DNS, IP intelligence, subnetting, reachability, and evidence triage.

This consolidates the fastest daily checks for network engineers, sysadmins, SOC analysts, and support teams into one Next.js interface. Use it for first-pass investigation before you pivot to heavier tooling.

Recommended next checks

Run the DNS tab to verify authoritative records, MX paths, and TXT policy data.
Use the Web Reachability tab for direct browser probe results and to see whether the target is readable or blocked by CORS.
Use the Operations tab for public IP context, resolved target IP, geolocation, and safe frontend-only network tools.
Use the Addressing tab for quick capacity checks or to validate an affected subnet during incident response.
