Why is URL being translated to numeric IP?

This is not my server, but my friend needs help with this problem:

When I go here: http://www.daveroels.com/gallery the URL gets automatically translated to the numeric IP address in the address bar of the browser.

But if I go here: http://www.daveroels.com/gallery/ then the address does NOT get translated.

Can anyone tell me what is causing this and how I can fix it? I do NOT want the URL to be translated into the numeric IP just because the trainling slash is not typed.
Thanks!
