Now, I have no idea for this. but I think we can add some note for the logic at least, and supply an interface for users to set just use the first ip or poll ips. default can be poll ips like now logic.

Maybe we can do some thing for ips load balancy, but it has a little hard. ^.^

** [bugs:#1271] connect time is half of my setting**

hi,
in curl-7.31.0, the timeout of connecting addr  is the half time of my setting with CURLOPT_TIMEOUT_MS or CURLOPT_DNS_CACHE_TIMEOUT when the addr has more than one ip.
in code, here is:
lib/connect.c 
Line 816:
  conn->timeoutms_per_addr = conn->ip_addr->ai_next == NULL ?
                             allow : allow / 2;
Line 1121:
    conn->timeoutms_per_addr = curr_addr->ai_next == NULL ?
                               timeout_ms : timeout_ms / 2;
so, it works don't like I expected.   Maybe there are some reasons that I don't know. 
 I want to connect use the total time as the timeout. I think curl can supply an interface that set by curl_easy_setopt.
how do you think?
