-t querytype

                Allows you to specify a particular querytype of information
                to be looked up.  The arguments are defined in the man page
                for named(8).  Currently-supported types include: ``a,
                ``ns, ``md, ``mf, ``cname, ``soa, ``mb, ``mg,
                ``mr, ``null, ``wks, ``ptr, ``hinfo, ``minfo,
                ``mx, ``uinfo, ``uid, ``gid, ``unspec. Additional-
                ly, the wildcard, which may be written as either ``any or
                ``*, can be used to specify any (all) of the above types.
                Types must be given in lower case.  Note that the default is
                to look first for ``a, and then ``mx, except that if the
                verbose option is turned on, the default is only ``a. The
                ``-t option is particularly useful for filtering informa-
                tion returned by host; see the explanation of the ``-l op-
                tion, below, for more information.
