Pre-release

This release is a pre-release and may not be stable for production use.

https://secure.travis-ci.org/saghul/aiodns.png?branch=master

aiodns provides a simple way for doing asynchronous DNS resolutions using pycares.

Example

import asyncio
import aiodns

loop = asyncio.get_event_loop()
resolver = aiodns.DNSResolver(loop=loop)

async def query(name, query_type):
    return await resolver.query(name, query_type)

coro = query('google.com', 'A')
result = loop.run_until_complete(coro)

The following query types are supported: A, AAAA, ANY, CNAME, MX, NAPTR, NS, PTR, SOA, SRV, TXT.

API

The API is pretty simple, three functions are provided in the DNSResolver class:

  • query(host, type): Do a DNS resolution of the given type for the given hostname. It returns an instance of asyncio.Future. The actual result of the DNS query is taken directly from pycares. As of version 1.0.0 of aiodns (and pycares, for that matter) results are always namedtuple-like objects with different attributes. Please check the documentation for the result fields.

  • gethostbyname(host, socket_family): Do a DNS resolution for the given hostname and the desired type of address family (i.e. socket.AF_INET). While query() always performs a request to a DNS server, gethostbyname() first looks into /etc/hosts and thus can resolve local hostnames (such as localhost). Please check the documentation for the result fields. The actual result of the call is a asyncio.Future.

  • gethostbyaddr(name): Make a reverse lookup for an address.

  • cancel(): Cancel all pending DNS queries. All futures will get DNSError exception set, with ARES_ECANCELLED errno.

Running the test suite

To run the test suite: python tests.py
