If you want a nice example of a domain name which is not a DNS name,
add in your /etc/hosts (or equivalent for your OS):

104.20.1.85 veryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongname.example.com

It is not a DNS name (first label is too long) but it works fine for
several applications which expect domain names:

% ping -c 3 veryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongname.example.com
