LinuxQuestions.org - Need explanation of resolveip results

Hi! I'm running FC4 and I need some help interpretting results from the system command "resolveip." What do these different results mean in terms of how the domain name is functioning?

Code:

$ resolveip firstdomain.com

Broadcast

$

Code:

$ resolveip seconddomain.com

resolveip: Unable to find hostid for 'seconddomain.com': try again

$

Code:

$ resolveip thirddomain.com

resolveip: Unable to find hostid for 'thirddomain.com': host not found

$

Code:

$ resolveip fourthdomain.com

resolveip: Unable to find hostid for 'fourthdomain.com': no_data

$

Am I right in assuming the third result means that thirddomain.com isn't registered anymore?
