nslookup is depricated, but I still find the output more readable than
dig.

lira-21: nslookup www.caltech.edu
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
