Which IPs does Report use?

For conducting automated checks, the Report system uses the following IP addresses:

• 51.15.195.57 (Broken Links Check)

• 163.172.163.254

• 51.158.127.67

• 185.192.99.60 (Debugging)

Among other things, the system checks for so-called broken links – these are defective or invalid hyperlinks that lead to unreachable web pages (e.g., with a "404 Not Found" error). Such links negatively affect user experience and can harm search engine rankings.
