that does not help you much in case as example a multi-postfix-installation
when the software is not interested in using a different port and you
want simulate real world by different IP's, binding services to specific
ones and work with *hostnames* via /etc/hosts
Then add multiple address aliases to the existing loopback interface. Either
way, theres really no reason at all to create multiple loopback interfaces
