They'll probably run leafnode on a machine like news.localhost.com,
which will not be subject to these restrictions.

No, leafnode should not roll any dice to figure a domain. Systems that
want network connectivity need a proper configuration. Period.

It is supposed to catch these cases, complain and refuse to work. That's

People MUST use a proper domain, see the pertinent Message-ID
FAQs. Usenet access does impose higher requirements on the configuration
than a "play tuxracer" machine. Such is life. There are many free domain
forwarders, Message-ID domains, ISPs offer unique domain names even
though they don't map, news.cis.dfn.de offers this, so there's really
enough choice to get a FQDN. Remember, we don't need DNS, we only need
to make sure the domain is unique.

If need be, we might be able to offer ID-1278234.users.leafnode.org and
possibly ask Thomas Hochstein or some other person for a registration
software (CGI for web server maybe) for these domains, but Cornelius has
to decide on this, because he owns leafnode.org.

However, I don't see an urgent need to do this with the leafnode.org
domain, there are enough services out there.
