Hans, learn the difference between a (Full Qualified) Host Name and a
Domain Name. mydomain.tld is a subdomain. It _may_ have an A record with
an IP address also, but usually it is only a domain with no IP address
associated. Where www.mydomain.tld is a FQDN leading to an A record with
an IP address or an CNAME alias. IP numbers refer to hosts (FQDN) and
vice versa. Hosts are the leaves in the hierarchical DNS name space
tree, where domains are branches in the name space. Services run on
hosts so myserver.mydomain.tld is the correct way.

p.s. Zum Gl?ck kennst du ja meine spezielle Art der Freundlichkeit. ;-)
