When calculating a domain name's DNP Score, because
of the nature of our complex algorithm, a domain name must be registered. We
check a domain name's settings, for example, that require that a domain name be
registered and owned by someone (or an organization). Domain names must be
'registered' with an accredited domain name registrar in order to work, and
unregistered domain names won't be reachable if you were type them into a web
browser to visit them.
Keep in mind that unregistered domain names can still
have problems associated with them, as they could be previously used for spam
or illegal activities in the past. Even though we do not report a DNP Score for
unregistered domain names, we highly recommend that you consider performing a
full domain name background check before registering and using any domain name for
email or for a website.
