<P><STRONG>WARNING!!!</STRONG> Don't assume the RR objects you receive from a query
are of a particular type -- always check an object's type before calling
any of its methods. If you call an unknown method, you'll get a nasty
warning message and <CODE>Net::DNS::RR</CODE> will return <A HREF="../../../../lib/Pod/perlfunc.html#item_undef"><CODE>undef</CODE></A> to the caller.</P>
