127.0.0.1 is localhost. Meaning the computer the site is hosted on. If you take out that IP, scripts on the site that you want to run, may end up getting blocked.
^192.168. is a non-routable subnet. Meaning, this is for Local Area Networks. Often, a hosting provider will place a large collection of servers behind a NAT Firewall to help prevent against port-based hacks. Again, don't remove that address as it may break things if you do.
As far as the access attempt goes, that looks spoofed. In other words, someone is hiding their real IP and User Agent (browser).
It looks as though they are just sniffing around. They are trying to see if you have fancy indexing turned on.
Make sure your modules are up to date, protector is installed and configured properly, your files and folders are chmod as restrictive as functionally possible, make sure you have an index.html in all writable folders with the following code in it
<script>history.go(-1);script>
For added protection, either turn off indexing through cPanel (if you have it), or add this .htaccess file to your site
OptionsĀ -Indexes

Insanity can be defined as "doing the same thing over and over and expecting different results."
Stupidity is not a crime. Therefore, you are free to go.
