What this tool does
Connectivity Checklist helps with walk through common network troubleshooting checks in a structured workflow. Use the Connectivity Checklist tool when you need this operation in a browser without installing another application. The page explains the supported input and gives explicit feedback when an input cannot be processed.
How to use it
Choose the symptom and follow the suggested checks. Mark a check only after you perform it. Copy the checklist to your incident notes and record actual command output, device details and timestamps separately.
Start with a small, representative input so that the result is easy to inspect. Keep a copy of the original before changing or exporting anything. If the output will be used in a production workflow, compare it with the expected behavior in that system rather than assuming a successful conversion proves correctness.
Understanding the result
No packets are sent and no commands run. A checked step means reviewed, not passed. Commands are examples for your environment; unanswered traceroute hops and missing PTR records do not independently prove a network fault.
A result reflects the supplied input and selected settings. An empty finding list, a missing optional property or a valid syntax result can be useful, but each has a limited meaning. Review messages and individual fields in context. Where the tool creates configuration, a command or a document, open or inspect the output before replacing an existing file.
Privacy and practical limits
Processing runs locally in your browser. Tool inputs and document contents are not sent to site analytics. Copy and download actions happen only when you request them; clipboard contents and downloaded files can contain sensitive data.

Before using an export
Confirm that the output belongs to the correct source and that important fields, page order or values match your intention. Save the source separately for future edits. When collaborating, share only the portion needed for the task, especially when logs, credentials or personal metadata are involved. The guide and tool describe a focused operation and cannot establish the correctness of an entire application or document.
