Website visitor log is showing six instances reflected as only a single dot in the ip address/hostname field (Apache, cPanel Linux, PHP 7.1 on shared host). Same user agent ("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36") and GET requests for six different single web pages in the six instances on four dates within the past month. Shared hosting technical support could only speculate the single dot was a cPanel glitch handling a proxy request.
Shouldn't the request be refused if Remote_Addr or Remote_Host cannot be identified? Any other possible explanations? Suggestions for .htaccess code to block a single-dot ip address or hostname?
