example.com (and also example.org and example.net) _is_ invalid. They are meant for, well, examples, and MUST be rejected if ever anyone attempts to connect to them. This is part of the definition of the Internet.

Best regards,

@vim-ml example.com is used as an example. In reality, I used a domain that is resolvable on my system. The use of example.com in this ticket is exactly the use case for it. Let's not derail this.
