Asynchronous DNS for Python asyncio (pure Python)

asyncdns's Issues

Can I do bonjour service discovery with this ?

I am using python zeroconf for getting the ip address of a local device with a specific mdns/bonjour name.

Something comparable to:
https://github.com/jstasiak/python-zeroconf#how-do-i-use-it

Is this library suited for doing this too ?

Example does not work

Description

I have tried running this example:

import asyncdns, asyncio
resolver = asyncdns.SmartResolver()
loop = asyncio.get_event_loop()
query = asyncdns.Query('www.example.com', asyncdns.A, asyncdns.IN)
f = resolver.lookup(query)
loop.run_until_complete(f)
print(f.result())

but this results in

;; Query refused ()

This seems to be a problem in asyncdns.SmartResolver. Switching to asyncdns.SystemResolver results in

;; No error (RD, RA)
; 1 answers:
www.example.com 50006   IN      A       93.184.216.34

Needs more tests

We need to add more tests.

Allow forced TCP

Hi, I'm looking to use this library in AWS Lambda which does not allow UDP sockets. Is there a way we can force TCP protocol to be used? Thanks.

Customize connection timeout

Hi there,

I'm trying to use the library to perform massive queries to DNS servers, so customizing the timeout is critical. I had to modify the code and change the TIMEOUT constant in resolver.py, but I was wondering if there is a better way to do it. If not, does it make sense to modify the lookup method to allow an optional timeout parameter? Would you accept a PR with this change?
