General DNS Resolution
The DNS service enables visitors to access your service resources, such as ECS, OBS, RDS, and ELB using domain names.
Tens of millions of concurrent queries on a single node
Supporting all of the most commonly used record types
You can create public and private zones for the same domain names to deploy your website both online and offline with the same code, facilitating service maintenance.
Deploy the same services online and offline. Offline changes can be seamlessly updated online.
Test the offline service in a VPC without interrupting online applications.
You can map private domain names to ECS IP addresses in specified VPCs, allowing these ECSs to communicate with each other using domain names.
Once an ECS is faulty, you only need to change its IP address in DNS records, instead of modifying existing configurations.
Private domain names are not exposed to the Internet so you do not need to worry about DNS spoofing and attacks.
A private DNS server directly responds to requests for private domain names, greatly reducing network latency.
Customize any domain names in VPCs.
Associate one DNS zone with multiple VPCs to simplify service deployment and management.
Create PTR records for ECS private IP addresses.
Receive responses directly from an internal DNS server for private domain requests, for example, to access ECSs in VPCs and services like OBS and API Gateway, accelerating name resolution and preventing DNS spoofing.
Stable, secure, and swift DNS resolution
Rich features, such as PTR records, DKIM, and wildcard DNS records
Multiple record types, including A, AAAA, MX, CNAME, TXT, NS, PTR, and SRV
