I still don't see why you would need multiple IP addresses for services
on a single physical server. It would usually be enough to handle this
as
virtual hosts on the application level rather than the OS level:
https://httpd.apache.org/docs/current/vhosts/
http://www.postfix.org/VIRTUAL_README.html
In that case, you only need to worry about CNAME and MX records in DNS.
