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 ()
; 0 answers:

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

System Info

I installed asyncdns through

pip install git+https://github.com/al45tair/asyncdns.git

I use conda to handle my dependencies. The output of conda list is:
