Why You Shouldn't Link to Unregistered Domains in Documentation

What are unregistered domains?

Unregistered domains are domain names that are not currently owned or registered by any individual or organization. Common examples include placeholder domains like example.com (although this is actually registered by IANA), company.internal, or mydomain.local.
