Multiple hostnames in the config.php for load balancing / round robin

[SnapOff Racing]

I am wondering if under the ****** MASTER DATABASE SERVER NAME AND PORT ****** I can add multiple hostnames that will point to one server that is hosting the database but yet that same server has 3 different WAN connections pointing to it. So basically it would look like this in config.php

// ****** MASTER DATABASE SERVER NAME AND PORT ******
// This is the hostname or IP address and port of the database server.
// If you are unsure of what to put here, leave the default values.
$config['MasterServer']['servername'] = '123.123.123.1';
$config['MasterServer']['servername'] = '123.123.123.2';
$config['MasterServer']['servername'] = '123.123.123.3';
$config['MasterServer']['port'] = 3306;

Will vbulletin automatically round robin these entries or will it only use the first connection and then just ignore the rest??
