Oct 20 2025
Alibaba Cloud DNS (DNS)Content
Applicable customers: Users who host public domains and want full lifecycle monitoring for their business‑critical domains. It monitors the NS delegation chain, authoritative resolution, recursive resolution, and anomalies such as TTL tampering and invalid delegation. When an issue is detected, the system sends timely alerts to help you identify and respond to risks. New features: 1. Core monitoring scenarios DNS resolution hijacking: Detects unauthorized changes or redirections to malicious destinations. DNS resolution hijacking: Monitors DNS server availability and responsiveness to prevent failures caused by server issues. Resolution latency: Tracks DNS response time trends to surface user experience problems early. TTL tampering: Detects abnormal TTL changes that could cause cache expiry issues or be abused. Global propagation validation: Verifies global propagation after DNS record changes to ensure updates take effect globally. Domain transfer/deletion protection: Monitors registry lock states (prohibit delete/transfer/update) to prevent malicious transfer, modification, or deletion. 2. User value Ensure business continuity: Real‑time visibility into the DNS resolution chain keeps services available. Improve user experience: Track and optimize DNS latency and improve user experience. Strengthen security: Detect tampering and misconfigurations to mitigate DNS hijacking and malicious redirects. Boost O&M efficiency: Multi‑metric monitoring, active probing, and alerting reduce manual inspections. Enable proactive operations: Shift from reactive fixes to early intervention that limits incident impact.
