Hi Pim,

the trailing '.' has a very spezial meaning. In hostnames it is simply not
allowed. So in /etc/hosts you will not find it.

If you ask 'name' then /etc/hosts will be the first to answer.
If you ask 'name.' then only DNS will answer. Some browsers and all
mailer do this.

For DNS (the resolver lib) that '.' means this is an FDN. Dont add the
search path to it. That is very importan for the Bind DNS server data
files.
