===================================

|
**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
