The IP is the address of some device. It can be your server and your server can indeed have multiple IPs but what's at that IP and what protocol determines what happens next.
In your case I'm GUESSING you want a list of files to show up like some small file explorer but over a web browser. For that, your server would have to do that. This is not as trivial as you wanted it to be so to me, Virtual Directory is not my path here.
However this is specific to your web server. If you are using Microsoft's own read:

I would like to have my intranet user PC to access the server shared folder in Chrome browser.
You might wonder why I need to do this instead of accessing folder in the network drive thru File Explorer. Or just copy and paste the link, the Chrome browser will open for me. Well, I hosted a web application embedding iframe for accessing website "inside" the web application, just like you can open web link inside application without leaving your mobile app on phone. I tried simply put "file://" in the iframe source, it does not work.
I googled and found the Virtual Directory might be a solution, but it seems that "Virtual Link Alias" only work on the server where the shared folder physically located.
My question is how to allow other client PC in my local LAN accessing the server share folder by using Virtual Directory or what would you suggest?
