Domain Name Service

Domain Name Service (DNS) provides highly available and scalable authoritative DNS resolution services along with domain name management. It translates domain names into IP addresses required for network connection to route visitors to desired resources.

This free service is enabled by default for all HUAWEI CLOUD users.

You can map ECS IP addresses to private domain names in specified VPCs, allowing these ECSs to communicate with each other using domain names.

Advantages

No Code Modification

If an ECS becomes faulty, you only need to change its IP address in the DNS records, instead of modifying existing configurations.

Free from DNS Spoofing

Private domain names are not exposed to the Internet so you do not need to worry about DNS spoofing and attacks.

High Performance

A private DNS server directly responds to requests for private domain names, greatly reducing network latency.
