Answer: To filter traffic based on domain names rather than IP addresses
Explanation
Cilium's DNS-based policies allow you to filter traffic based on domain names rather than IP addresses. This means you can create policies that allow or deny access to specific domains (like 'example.com') regardless of their IP addresses, which can change over time. This is particularly useful for controlling access to external services.
