[URGENT BUG] HTTP tests are failing for IP address based tests

  - # Image API
    type: site
    url: http://10.20.30.40:9292/v2/
    expect:
      status: 401

is failing with the following error;

gaierror: -2

because you're trying to resolve it, as a dns name, into an IP address. But it is already an IP address.

Also it might be because of the port number there.
