DNS Route Leak Guard

机器辅助翻译草稿 (Chinese) for "DNS Route Leak Guard": DNS Route Leak Guard is a networking routing control that detects and blocks accidental route propagation for name resolution and delegation. It uses prefix filters, validation, and peer policy so teams can protect reachability while keeping evidence, reliability, and public-safe operational boundaries clear.

“示例草稿: The network engineering team used DNS Route Leak Guard when a resolver returned stale data, so the team could protect reachability before traffic crossed a service boundary.”
