The same goes for domain names; do NOT use a public domain name you do not control in your configuration, documentation, or UI language.
Instead, use one of the available reserved domain names documented in RFC 2606, such as 'example.com', 'example.net', or the .example top-level domain.
❌ test.com
❌ yourdomain.com
✅ example.com
✅ yourdomain.example
Pass it on to your fellow developers, designers, documentation writers, and so forth.
