I periodically try to get the name of vendor and product identification
about load balancer vendors that return broken DNS responses.  This
is after pointing out that the load balancer is broken and saying
why I want it (to inform the vendor / warn others not to purchace
a broken product).  Invariably the administrator is too paranoid
to supply the information.  The best one can hope for is to have
the operator contact their supplier.
