What Are Huawei Cloud Private DNS Server Addresses?
What Are Huawei Cloud Private DNS Server Addresses?
Updated on 2024-05-30 GMT+08:00
Private DNS servers are used in VPCs to:
- Resolve private domain names and internal domain names of cloud services.
- Forward domain name requests to public DNS servers.
You can use private DNS servers provided by the DNS service to:
- Resolve private domain names used in VPCs.
- Access cloud services such as OBS and SMN.
- Allow ECSs without EIPs to access the Internet.
Table 1 lists private DNS server addresses provided by the Huawei Cloud DNS in different regions.
- Set the DNS server addresses of the VPC subnet where the ECS resides to the private DNS server addresses of each region. For details, see How Do I Change Default DNS Servers of an ECS to Huawei Cloud Private DNS Servers?.
Table 1 lists the private DNS server addresses in each region.
- If you set DNS Server Address to external DNS server addresses, traffic will be routed to public IP addresses when ECS accesses other cloud services, which may incur additional traffic fees.
- When an ECS accesses a third-party domain name on the Internet, the private DNS server functions as a recursive DNS server, and the authoritative DNS server returns the final resolution result. Whether the resolution result is reliable or optimal depends on uncontrollable factors such as third-party authoritative DNS. It is recommended that ECSs access cloud services using their private domain names.
