Reminder that the only safe dummy domains to use are:

- example.com
- example.net
- example.org
- example.edu

And nowadays there's also a safe dummy TLD: .example

These are safe because they are reserved by IANA as as special-use domain names for documentation purposes.

Any other domain can be registered and as such should _never_ be used as a dummy domain for documentation or as eg. an example in default configs.
