Question regarding DNS resolution in urllib2

hi ,

I trying to use urllib2 in my script , but the problem is lets say a domains resolves to multiple IPs , If the URL is served by plain http , I can add “Host: domain” header and check whether all IPs are returning proper responses or not , but in case of https , I have to trust on my local machines dns resolver and I can’t apply host header in the request . 

Is it possible to override dns resolver in urllib2 or something else ? 

>>> req = urllib2.Request(url='https://google.com/')
>>> f = urllib2.urlopen(req)
>>> print f.read()

I wanted to control the IPs which urllib2 is trying to connect . 


I Hope I am some sense out of my question , 

Thanks in advance.
