I think you're thinking of whois.

For example, it tells me that your first example ( comes
from an address range assigned to telstra.

If you're stuck on a machine without access to a whois utility (e.g. a
friend's windows machine), there are websites that will do the work for
you.  One example is http://ws.arin.net/cgi-bin/whois.pl
