Extracted forged IP's from GFW, and possible China Telecom:
>>> a=[__import__('DNS').Request().req('twitter.com', server='61.139.2.69').answers[0]['data'] for x in xrange(10000)]
and they are:
202.106.1.2
202.181.7.85
203.161.230.171
209.145.54.50
211.94.66.147
216.234.179.13
4.36.66.178
64.33.88.161
btw, IMO pydns module is much better than dnspython.
