Terms of use

The information on this site is provided for general educational purposes. DNS and email changes can interrupt production services, so readers are responsible for validating commands, provider requirements and backups in their own environments.

No guarantee

We work to keep material accurate and useful, but do not guarantee that every example applies to every registrar, DNS provider or mail platform. The site is provided without warranties to the extent permitted by applicable law.

Acceptable use

Do not attempt to interfere with the site, bypass access controls, probe private administration services or use the content to operate systems without authorization.

Third-party services

References and links to registrars, DNS platforms, certificate authorities, mail providers and advertising services do not imply endorsement. Their separate terms apply.

Updates

These terms may be updated as the site changes. Continued use after an update means the revised terms apply.
