Subdomain Management Supports independent authorization management for second-level and third-level subdomains. The number of DNS records for subdomains is unlimited. Minimum TTL Allows you to set the minimum time to live (TTL) to 1 second for the changes to DNS records to take effect. Load Balancing Supports up to100 IP addresses that are used for load balancing in a single line of a domain name. Weighted Round-robin Supports A and CNAME records. Query Statistics Collects statistics of DNS queries for primary domain names and subdomain names.
Intelligent DNS Resolution
ISP Lines Supports China Unicom, China Telecom, China Mobile, CERNET, Dr. Peng Telecom & Media Group, and China Broadcasting Network. Subdivided ISP Lines Supports 6 major ISPs, which cover 31 provinces. Region Lines Supports Central China, North China, Northeast China, East China, South China, Southwest China, Northwest China. Subdivided Region Lines Supports 7 regions in China, which cover 31 provinces. Lines Outside China Supports Oceania, Asia, Europe, North America, South America, and Africa. Subdivided Lines Outside China Supports 6 continents, which cover 88 countries and regions. Custom Lines Supports intelligent DNS resolution for lines based on custom IP address ranges.
DNS Security
DNS Query Attacks Supports real-time attack detection and abnormal traffic handling, and processes up to hundreds of millions of DNS queries per second.
Secondary DNS
Disaster Recovery and Backup Secondary DNS provides disaster recovery and backup for your DNS. If your DNS server fails, the secondary DNS server can continue to provide DNS services to ensure that your business system is still accessible. Load Balancing To achieve load balancing, you can use the secondary DNS server and your DNS server to provide DNS services at the same time. To protect your DNS server, you can use only the secondary DNS server to provide DNS services. Secure and Effective Resolution Secondary DNS provides efficient DNS services based on the global node distribution of Alibaba Cloud DNS, and protects your websites or applications against DDoS attacks.
DNS Monitoring
Wide Coverage of Nodes Deploys more than 1,000 nodes in China. These nodes are distributed in the provinces and regions of major ISPs in China. Real-time Monitoring and Alerting Performs 24/7 monitoring to promptly identify exceptions and send alerts to O&M personnel. DNS Hijacking Mitigation Monitors the domain name hijacking status in real time to reduce the probability of DNS hijacking to a certain extent. Rapid DNS Resolution Reduces the recursive process of public DNS servers to accelerate DNS resolution.
DNS over IPv6
IPv6 Support Supports IPv6-based AAAA records and provides DNS servers that support access from IPv6 addresses.
Batch DNS Resolution
Fast and Efficient Processing Improves DNS resolution efficiency by processing batch tasks asynchronously in the background at high speed. Up to 10,000 DNS records can be processed within 10 minutes. Comprehensive Features Provides flexible batch DNS resolution. You can add, modify, and delete multiple DNS records at a time. It also allows you to manage domain names in groups, host domain names that are not registered at Alibaba Cloud, and delete multiple domain names at a time. Capability Opening Uses APIs that are dedicated for batch DNS resolution. These APIs are used for custom DNS resolution and provide you with reliable domain name resolution capabilities.
