Hi all,
Windows tends to report a couple of IPv6 DNS servers that don't actually
exist; they all start with `fec0:0:0:ffff`. It takes a while for c-ares to
figure out that these DNS servers are not responding, so IPv6 lookups end up
taking a long time.
This patch fixes that. We've been using it for a couple of months within
Node.js and it seems to fix the problem without causing any new issues.
