Database entries stored in DNS servers with information on specific domains, such as their IP addresses or instructions on how to handle related DNS queries. DNS records are essential for translating human-friendly URLs to connection instructions for the user’s devices.
Devices store DNS records retrieved from DNS servers in their cache to avoid repeat DNS requests. Over time, this poses security and privacy risks — anyone with access to your DNS cache can see your online activity or redirect you to dangerous websites (DNS spoofing). For this reason, it is important to regularly flush your DNS cache.
