Is the hosts part needed

Hello, I am following the guide HERE to setup my own webserver.

What I want is to setup the webserver and ISPConfig 3 and then add my sites that way.

I'm stuck here..

Is 192.168.0.100 the IP of my machine? So I would edit it to 192.168.1.67?
Also is this part really nesessary since I do not want to configure a domain at this time?

I have a static external IP which points to my webserver after configuring my NAT router.

Or can I edit these parts once I am set up and ready to point my domain?

Thank you

 

Yes, it need to be done

 

Thank you, I am having a little trouble.

I am behind a NAT router but everytime I try to configure that file I loose internet connection.

I must be putting wrong IP addresses in or something.

I have configured my router and have a static IP address. My computer is assigned a static IP address everytime from my router 192.168.1.67

My public IP is 212.159.**.** which points to my server computer and I have opened the necessary ports.

By my original understanding I wanted my server and then ISP config to manage my sites so am I needed to enter a domain at this time?

Thanks for your reply
