Offending line is the the 4th.

When I print the value of the variable 'host' in urllib2.py line 1301
I get this: somerandomhost.ontheinternet.com. This is why
socket.gethostbyname(host) raises gaierror -5, there is no address
associated to somerandomhost.ontheinternet.com. Instead the values
that 'host' takes for the other urls are localhost or 127.0.0.1, both
valid for gethostbyname().

Any hint?

Thanks.
