> The default setting of the configuration parameter {{client.dns.lookup}} is *not* {{use_all_dns_ips}} .  Consequently, by default, if there are multiple IP addresses and the first one fails, the connection will fail.
>  
> It is desirable to change the default to be {{client.dns.lookup=use_all_dns_ips}} for two reasons:
>  # reduce connection failure rates by 
>  # users are often surprised that this is not already the default
