Unbound
|
|
-------
|
|
|
|
`Unbound`_ is an implementation of a DNS resolver, that performs caching and
|
|
DNSSEC validation.
|
|
Together with unbound, the libunbound library is provided.
|
|
This library can be used to convert hostnames to ip addresses, and back, as
|
|
well as obtain other information.
|
|
Since the resolver allows to specify the class and type of a query (A record,
|
|
NS, MX, ...), this library offers powerful resolving tool.
|
|
The library also performs public-key validation of results with DNSSEC.

pyUnbound
|
|
---------
|
|
|
|
The pyUnbound is an extension module for Python which provides an
|
|
object-oriented interface to libunbound.
|
|
It is the first Python module which offers thread-safe caching resolver.
|
|
|
|
The interface was designed with the emphasis on the simplicity of use.
|
|
There are two main classes :class:`unbound.ub_ctx` (a validation and resolution
|
|
context) and :class:`unbound.ub_result` which contains the validation and
|
|
resolution results.
|
|
The objects are thread-safe, and a context can be used in non-threaded as well
|
|
as threaded environment.
|
|
Resolution can be performed blocking and non-blocking (i.e. asynchronous).
|
|
The asynchronous method returns from the call immediately, so that processing
|
|
can go on, while the results become available later.

Features
|
|
--------
|
|
|
|
* Customizable caching validation resolver for synchronous and asynchronous
|
|
lookups
|
|
* Easy to use object interface
|
|
* Easy to integrate extension module
|
|
* Designed for thread environment (i.e. thread-safe)
|
|
* Allows define and customize of local zone and its RR's during the operation
|
|
(i.e. without restart)
|
|
* Includes encoding functions to simplify the results retrieval
|
|
* Internationalized domain name (`IDN`_) support

Application area
|
|
----------------
|
|
|
|
* DNS-based applications performing DNS lookups; the caching resolver can
|
|
reduce overhead
|
|
* Applications where the validation of DNS records is required
|
|
* Great solution for customizable and dynamic DNS-based white/blacklists (spam
|
|
rejection, connection rejection, ...) using the dynamic local zone
|
|
manipulation
