In the Digital Age, the DNS Resolution System Urgently Needs to be Upgrade
Modern enterprise networks are undergoing in - depth development towards intelligence, automation, and IPv6 adoption. How can we achieve DNS recursive standard requirements such as multi - link, application - level scheduling, and automated disaster - tolerant switching?
Three Major Advantages

Hundreds of Millions of Resolutions

It supports over 1,000,000 intelligent routes with big data support, and can perceive the resolution status in real time.
Intelligent Scheduling
There are over 10,000 devices connected to the network. It can perform over 100 million resolutions per minute and support 1,000 transactions per second.

Significantly More Reliable
The intelligent resolution algorithm enhances the business continuity level by more than 10 times. Meanwhile, it provides cross - regional technical support for over 60 regions across the country.
Intelligent Optimization, Dedicated to Every Single Resolution

Hundreds of Millions of Resolutions

- Record optimization based on applications and source IPs - Control the TTL (Time To Live) of specific domain names to prevent long - term cache expiration - Prefetch the caches of top - visited and key business domain names for low - latency and stable resolution
111
Link Disaster Tolerance Monitoring and Switching
- Real - time monitoring of the health status of upstream forwarding servers, with automatic fault isolation. - Automatically switch to the standby recursive source when the export link fails. - After a query failure, attempt to use the standby forwarding or perform self - recursive query.

Multi - exit Link Scheduling

- Linkage of network exit links to perceive real - time traffic bandwidth and dynamically adjust resolution weights. - Fine - grained scheduling in the form of a domain name library to achieve application - level resolution optimization. - Differentiated strategies for different time periods, achieving both link scheduling and a good user experience.
111
Dual - stack Resolution Optimization
- A wealth of dual - stack resolution control strategies to meet the optimization needs of dual - stack resolution in complex scenarios: - AAAA filter black and white lists - AAAA filter wild - card matching - Support for fine - grained DNS64 capabilities (prefix, suffix, mapping control, etc.)

Recursive Result Control

- Multiple forwarding methods such as RTT (Round - Trip Time) optimization and sequential forwarding - Source - based access control - Destination - based access control

Dynamic Identification, Safeguarding Business Security

Domain Name System Protocol Security

- 0x20, identifier/port randomization - DoT (DNS over TLS)/DoH (DNS over HTTPS) - DNSSEC (Domain Name System Security Extensions) - Non - standard protocol filtering
Domain Name System security capabilities
- Protection against local security policy reflection and amplification attacks - Protection against domain - name/zone rate - limiting cache snooping attacks - Protection against IP rate - limiting tunnel attacks - Servfail protection

Threat Intelligence Linkage
- Local interception, cloud - based intelligence synchronization & policy distribution
- Interception statistics
- Interception alert
- Interception log
