No, I was curious if you had a libcurl built to use c-ares and/or if you have
it built to support IPv6. A "curl -V" output would show. Since you use the
stock ubuntu version I'm pretty sure it isn't c-ares enabled.

I didn't see any failed system call for a resolve there.

As you're (most likely) not using c-ares, libcurl is using the "plain" name
resolver calls gethostbyname() or getaddrinfo() and if they fail I don't see
how it can be libcurl's fault... :-O
