How to redirect from the root to another page in apache?

Question

Apache HTTP Server

If I do this:

Redirect "/foo.html" "/bar.html"

then when I open ip/foo.html I see ip/bar.html, i.e. everything is working.
If the config is different:

Redirect "/" "/bar.html"

Then when I open the site by ip I see in the browser:
ip/bar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar.htmlbar. htmlbar.html
How to fix a redirect so that bar.html opens when accessing by ip?
IP can be any at the same time on the server of the client who will install the software.

Answer 1

RedirectMatch ^/$/bar.html
