Answer 1

You cannot open two web servers in the same port (which default is 80), if you desire to make two or more web servers, you have to use different ports.

If you are using a DNS, you could easily set up your web server to respond with different web sites to different requests, that could be useful if you need to have different web sites for subdomains or different domains.
