   4 Resolver only

   7 This example program shows how to perform DNS resolution only.
   8 Unbound contains two basic modules: resolver and validator.
   9 In case, the validator is not necessary, the validator module can be turned off using "module-config" option.
  10 This option contains a list of module names separated by the space char. This list determined which modules should be employed and in what order.

  28    The :meth:`unbound.ub_ctx.set_option` method must be used before the first resolution (i.e. before :meth:`unbound.ub_ctx.resolve` or :meth:`unbound.ub_ctx.resolve_async` call).
