Yes [see Rick's post], but that likely isn't going to do what you want. Most end-user client applications are simplistic, simply using the first IP address returned by the DNS server. The DNS server may order the IP addresses differently each time resolution is performed (round robin), but you can't really depend on it since it depends on the specific DNS server implementation. More sophisticated clients (often found in server-class clients such as SMTP) will use the entire list of IP addresses and try each in sequence until the connection succeeds or the list is exhausted.
