Resolver only
|
|
=============
|
|
|
|
This example program shows how to perform DNS resolution only.
|
|
Unbound contains two basic modules: resolver and validator.
|
|
In case, the validator is not necessary, the validator module can be turned off
|
|
using "module-config" option.
|
|
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.

|
.. note::
|
|
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).
