That is more a question on Apache configuration. What I can tell you is that MediaWiki needs a server - you can put the MediaWiki files somewhere on the computer, but as long as you do not run a webserver, in which the wiki files are located, the wiki cannot work. While you run the server, you can disconnect your computer from the internet, so that there is no way to connect to it from outside, while the wiki can function using the server you installed locally.

I guess you can test your configuration by opening the URL 127.0.0.1 in your webbrowser. If this shows the XAMPP example website, which the XAMPP developers have provided with the webserver, then it's working. If you ask me, I do not remember having to change this IP address somewhere in the Apache configuration. I think it might also work without such change...
