Simple DNS resolver for asyncio

aiodns provides a simple way for doing asynchronous DNS resolutions with a synchronous looking interface by using pycares.

Example

import asyncio
import aiodns

loop = asyncio.get_event_loop()
resolver = aiodns.DNSResolver(loop=loop)
f = resolver.query('google.com','A')
result = loop.run_until_complete(f)
print(result)

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

API

The API is pretty simple, two 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.
• 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 test_aiodns.py
