This works as expected. :-)

I'm downloading a large number of urls and the result is expected to have
failure reasons, DNS lookup failed being one.
calling lookup manually would solve my issue, I suppose. Just wanted to
make sure that I'm not missing any obvious solutions.
1. lookup DNS and if it succeeds,
2. try http.Ge
But AFIU, err.Temporary() could be true for other kind of errors that might
happen, isn't that a problem if I only want to handle DNS errors?

This is a question about the net/http API, Googling was not very helpful.
_, err := http.Get("https://random_non_existing_domain.com";)
Following code will obviously fail, but how can I check if it failed
because of DNS error not because a billion other things that might have
gone wrong?
