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.

import os
|
||
|
|
from unbound import ub_ctx,RR_TYPE_A,RR_CLASS_IN
|
||
|
|
|
||
|
|
ctx = ub_ctx()
|
||
|
|
ctx.set_option("module-config:","iterator")
|
||
|
|
ctx.resolvconf("/etc/resolv.conf")
|
||
|
|
|
||
|
|
status, result = ctx.resolve("www.google.com", RR_TYPE_A, RR_CLASS_IN)
|
||
|
|
if status == 0 and result.havedata:
|
||
|
|
|
||
|
|
print "Result:", result.data.address_list
|
||
|
|
|
||
|
|
.. 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).
