The domain name suffix used when fully qualified domain
names are not specified.
When no domain suffix is specified, you must use fully
qualified domain names. When a domain suffix is specified
you may use the host or node name portion of the domain
name when referring to domain names within the domain
sub-tree (suffix) specified by this object.
For example, setting this object to `xedia.com' allows
you to refer to the node `barbados.xedia.com' as
`barbados'.
For those familiar with the UNIX operating system, this
object is equivalent to the `domain' keyword in the
/etc/resolv.conf file. For example, setting this object
to `xedia.com' has the same affect as specifying `domain
xedia.com' in your /etc/resolv.conf file.
Values of this object must adhere to the rules for
domain names specified in RFC 1034 and RFC 1035.
