My mistake, I forgot how $dns functioned. $dns().nxdomain would suffice.
I definitely mean NXDOMAIN. I'm already fully aware of the whois registry as per my
whoisd.mrc script.
You are mistaken. A domain that exists that does not have an A line (non-resolvable) does not also return NXDOMAIN (non-existent).
Further more, I do not appreciate your condescending attitude.
