The reason for this is the way AI_V4MAPPED is handled. According to POSIX, AI_V4MAPPED should be ignored unless ai_family is AF_INET6: http://pubs.opengroup.org/onlinepubs/9699919799/functions/freeaddrinfo.html If the AI_V4MAPPED flag is specified along with an ai_family of AF_INET6, then getaddrinfo() shall return IPv4-mapped IPv6 addresses on finding no matching IPv6 addresses (ai_addrlen shall be 16). The AI_V4MAPPED flag shall be ignored unless ai_family equals AF_INET6. uClibc-ng was also handling AI_V4MAPPED for AF_UNSPEC, fix that.

Signed-off-by: Tim Hockin &lt;thockin(a)google.com&gt; commit 2ac8348609b63d6f3a87cb27ce17deff889c6a73 Author: Tim Hockin &lt;thockin(a)google.com&gt; Date: Wed Mar 9 21:48:32 2016 +0100 DNS: don't count search-path miss as a retry Currently a miss on a search-path entry is counted as a retry. This means that users with more than (num_nameservers * retries) entries in their search path list fail before trying all search paths. Concretely, a single nameserver with 4 search paths will never try the 4th search because the default retry is 3. The code doesn't currently retry a given nameserver in case of an error, so retries is sort of meaningless (though there are some comments indicating it might come). This change only treats total failure of a nameserver (try next server) as a retry.
