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?
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?

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

This works as expected. :-)
