How to host a server on a different IP address?

[Tmanyo]

So I would like to host a server in the future but the machine I want to use is not ready yet. So I want to use my current machine, but I do not want people going through my main IP. This computer can't handle a VM. Is there a way to have another IP that doesn't go to my main computer? My main reason is because of IP Hackers. Please help, if you are just here to hate, I don't need it. Thank you in advance. :)

Errr... Ok
First, You need to understand this :
the "web" => your router => your computer

And this :
You need to redirect clients from the web, through your router to your computer (with port forwarding), if you want, in future, change the computer wich is server, you just need to re-configure your router port forwarding. (if the computer still in your home, for this example it's the case)

Now, if you want to "protect" yourself against "hackers", if you don't have sufficient knowledge, the better way to host a server isn't inside your home connection but, if you haven't the choice, get informed about a strong security linux based OS (OpenSuse, CentOS, Debian), iptables, clamav, maldet, rkhunter, debsums, etc... and many other thinks :D

Thank you for this information, I know about port forwarding and the first part. I don't have the option to take it away from my home connection. So I will check out your suggestions. Thank you again. :D
