Tool objective
This tool helps prepare a structured review. It does not replace a complete technical validation, but it reduces common omissions before DNS, email, hosting or launch changes.
Practical tool
This estimate is indicative. It does not replace a real technical review.
Validate before applying
- Keep a copy of the current configuration.
- Test in a controlled environment when possible.
- Document who performs the change and when.
- Allow for DNS propagation time where relevant.
Tool limitations
The tool helps prepare a review or estimate. It does not replace a complete analysis of the real configuration, server logs, application constraints or provider policies.
Results should be treated as a starting point. Before applying a DNS, email or hosting change, review dependencies, keep the previous state and prepare a rollback option.
- Do not publish a DNS value without validation.
- Do not remove an old configuration before confirming the new one.
- Record changes and the time of modification.
- Test the website and email after each important change.
Frequently asked questions
Does the tool change any configuration?
No. It helps prepare a review or indicative value, but it does not change anything automatically.
