I'm running two multisite, meaning multiple sub domains handled by the same WordPress sites on a server using 2 NIC's, each with it's own IP address. Each domain name points to a different IP address.
I have seen references to multi homed or virtual IP addresses on E-E but most links are outdated and no longer work.
Does any one know how to create additional IP addresses so I can expand the number of websites? The server is vastly underutilized and it would be great if I can add more web sites on that same server.
