Supports 7 regions in China, which cover 31 provinces.
Supports intelligent DNS resolution for lines based on custom IP address ranges.
DNS Query Attacks
Supports real-time attack detection and abnormal traffic handling, and processes up to hundreds of millions of DNS queries per second.
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.
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.
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.
Public Recursive DNS
App Hijacking Prevention
HTTP-based DNS resolution bypasses local DNS servers and prevents cache pollution issues.
Multiple Access Methods
Supports access of apps and IoT devices through APIs and SDKs for Android and iOS.
Enables recursive DNS to work with authoritative DNS to update resolution results in seconds.
Global Traffic Manager
Allows you to perform protocol-based health checks to retrieve the status of application services through the ICMP, TCP, HTTP, and HTTPS protocols.
Multiple Access Policies
Supports access policies based on geographical locations and access latency to implement nearby access.
Supports load balancing between multiple IP addresses. This ensures that fault detection and failover can be completed within 1 minute at the earliest and guarantees the security and stability of application services.
Distribution of Nodes in China
China (Beijing), China (Shanghai), China (Shenzhen), China (Hangzhou), China (Heyuan), China (Zhangjiakou), China (Chengdu)
Distribution of International Nodes
China (Hong Kong), Japan (Tokyo), Singapore, Malaysia (Kuala Lumpur), India (Mumbai), Indonesia (Jakarta), Australia (Sydney), US (Virginia), US (Silicon Valley), Germany (Frankfurt), UK (London), UAE (Dubai)
Alibaba Cloud DNS covers full-process scenarios for users. It optimizes the entire DNS resolution process starting with the domain name access initiated by clients. Alibaba Cloud DNS provides policies such as cache prefetching and intelligent DNS resolution to improve website access experience and ensure the security and reliability of the full DNS process.
DNS Hijacking Prevention
Prevents the risks of local DNS cache pollution and DNS information leakage.
Fast resolution based on the cooperation of authoritative DNS and recursive DNS
DNS information is prefetched from clients and then pushed by Alibaba Cloud DNS, and authoritative DNS works with recursive DNS to reduce dependencies on third-party systems.
Backup for disaster recovery to improve business security
Supports various scheduling policies such as access based on geographical locations and access based on latency. Address pools are backed up to each other in advance to ensure business stability and continuity. The health check feature is provided to discover faults and perform failover quickly.
Guarantee of business stability and reliability
The DDoS mitigation system developed by Alibaba Cloud supports over 10 Tbit/s network bandwidth and multiple large-scale traffic scrubbing centers around the globe, which can easily deal with an ultra-large volume of DDoS attacks.
Defense Against DNS Query Attacks
For users of live streaming, video, games and social networking, DNS security + high anti-IP can be purchased and used together, and protection measures have been added in both the parsing request and the website site, so that the website will be more secure.
Prevents service interruptions caused by massive DNS resolution requests sent to victim DNS servers.
DNS Bounce-back denial-of-service attack with Broadband Exhaustion
Solve the problem that a large number of hosts forge the victim IP to send query request packets to a large number of open recursive DNS servers on the Internet, block the network of the victim DNS servers, and cause business interruption.
Hundreds of Millions of DNS Queries per Second
Resolves the issues of high business traffic and high QPS resolution requests in large-sized enterprises.
Fast, Stable, and Secure Terminal Access
Provides a fast, stable, and secure DNS resolution service for various terminals, such as mobile terminals, apps, and IoT devices in DNS over HTTPS (DoH) or DNS over TLS (DoT) mode.
Accelerated Terminal Access
Allows terminals to access the nearest nodes. Recursive DNS resolution is not required for access to about 50% of the domain names in China. Access to these domain names can be directly routed to the requested nodes.
Stable DNS Resolution for Terminals
Deploys hundreds of servers worldwide to provide sufficient bandwidths. This achieves stable access to nodes.
Efficient Anti-hijacking for Secure Access
Bypasses local DNS servers of Internet service providers (ISPs) to prevent domain hijacking and protect user privacy.
Interaction with GTM to Route Traffic to Acceleration Areas
Suitable for enterprises with cross-region and cross-border business, such as international enterprises expanding business in China and Chinese enterprises with overseas business.
User Access Acceleration
To accelerate Internet access, Alibaba Cloud DNS and Global Traffic Manager (GTM) can work together to route traffic to acceleration areas that are deployed with Global Accelerator (GA) and nearest to users.
Health Check and Failover
GTM provides health check and failover capabilities for the acceleration areas of GA and origin servers. This improves the security and stability of enterprise websites.
Fast Disaster Recovery Design
Interaction between Alibaba Cloud DNS and GTM is cost-effective and easy and needs a short preparation period. Enterprises can efficiently build the disaster recovery architecture without the need to change the existing website architecture.
