I remember something like the host command:

host -l <domain>

which was like your ls command for hosts under that domain.  If I did host 
-l slashdot.org, slashdot's domain server would give me an exhaustive list 
of everything slashdot.

but it seemed over the years, people considered that a security risk and 
told everyone to turn it off.
