If a domain is specified in /etc/resolv.conf, it will be used.
If hostname is set to be a value that contains at least one period (.), the value to the right of the first period will be used as the domain value.
The domain listed in /etc/resolv.conf has precedence over the hostname value if both a domain and hostname are available.
If both NIS and DNS results are non-null, a case-insensitive comparison is performed with the domain listed on the license. If the domain value from the license is a subset of either the NIS or DNS values, the license will be granted.
The licensed software operates as long as the requesting user of the licensed software is on a valid network domain.
