On a modern Linux system you would
check what you've got ip addr
add a new IP ip addr add ...
You can do things like cp -a /etc/sysconfig/network-scripts-icfg-eth0 /etc/sysconfig/network-scripts-icfg-eth0:0 (then edit the new file with the correct details)
or whatever your startup scripts look like

Not sure I understood the question but yes you can have as many IPs as you want on the same nic.
It's been a while since I have done it but you just add virtual nics and they look like this:
Eth0:0 Eth0:1 Eth0:2 Etc. Each one has its own Mac and can operate independently on the network. They can all be static IPs or dhcp.
They can even be on different vlans.
