It's not one of the ip's in my ip pool. Using CentOS + CPanel. You can see it use the incorrect ip right upfront when it issues a self-signed ssl cert. I tried editing the ip:post in the config file to no avail.

Any ideas?

I believe I recall answering this in a support ticket from you a few days ago, but for anyone who's wondering, we get it from the output of 'ifconfig'.  As I mentioned in the ticket, CPanel doesn't necessarily give you a canonical list of the IP addresses configured on your server.  ifconfig does.
