Secure and Reliable
- You can associate a custom resolution with a specific VPC. The resolution is effective only within that VPC and cannot be queried from any unassociated VPCs. This defines the access boundary of your internal systems and restricts core data access to the minimum scope.
- VPCDNS cannot be queried from the Internet, preventing external malicious probing of your internal service information and system architecture.
- By leveraging network tunneling features, your VPCDNS data is protected against malicious cracking.
High Scalability
The VPCDNS components are stateless and deployed on virtual machines, supporting rapid, smooth horizontal scale-out.
Unified Management
One private domain can be associated with multiple VPCs to facilitate unified management and deployment.
Comprehensive Recording
Various record types are supported, including A, CNAME, MX, AAAA, TXT, PTR, SRV, and SPF, catering to diverse DNS resolution configuration scenarios.
Reverse Resolution
You can set reverse resolution by creating a fixed private domain ending with in-addr.arpa and adding a PTR record.
Subdomain Recursive Resolution
When the subdomain recursive resolution setting is enabled, subdomains not configured will automatically be forwarded to the default recursive domain server for resolution.
