Get the short or long hostname
SysHostnameFQDN uses the host ‘C’ library to discover the usually short host name, then uses perl gethostbyname to extract the real hostname.
The results from gethostbyname are exported as gethostinfo and asciihostinfo as a convenience since they are available. Similarly, the ‘C’ library functions inet_ntoa and inet_aton are exported.
