load balancing question

Hi, we are trying to load balance MU across multiple servers

for example:

http://174.129.42.233/blogs/spreadtheword

and

http://107.22.183.251/blogs/spreadtheword

are exact copies, however something in my configuration is redirecting everything to:

http://yovia.com/blogs/________________

I have updated my wp-config.php file to point to the IP which didn’t cause any problems:

define(‘WP_SITEURL’, ‘http://174.129.42.233/blogs/’);

However, because the domain is set to yovia.com, it tries to redirect both installs to yovia.com/blogs

define( ‘MULTISITE’, true );
define( ‘SUBDOMAIN_INSTALL’, false );
$base = ‘/blogs/’;
define( ‘DOMAIN_CURRENT_SITE’, ‘yovia.com’ );

If I try to change ‘yovia.com’ to an IP it gives me database errors. Anyone know how to handle just getting WordPress to run without the domain being hardcoded?
