Underscores in host names

Hmm, they've always teached to me that . (dot) at the end of hostnames indicates the (hidden) Root domain:

blah.domain.com.[Root]

And my teachers always said that we don't need to write the final . because every domain belongs to the Root domain.

As for DNS servers for the Root domain, they are the reason for putting that "hint" files into our /var/named directory, "non"?

Because programmes like
check_soa from the O'Reilly book "DNS and BIND" or
sendmail
believe it makes sense to force a dot at the end of
every name they look up.

There are nameservers in the root zone file that DNS will
not find. /etc/hosts is the only way to get them.
Dont forget to have both names with and without dot.
