What Are Huawei Cloud Private DNS Server Addresses?

Private DNS servers are used in VPCs to:

  • Resolve private domain names and internal domain names of cloud services.
  • Work as a proxy for requests to public domain names.

Compared with public recursive DNS servers (for example, 114.114.114.114), private DNS servers provided by the DNS service can:

  • Resolve private domain names used in VPCs.
  • Enable access to cloud services such as OBS and SMN.
  • Allow ECSs without EIPs to access the Internet.

Table 1 lists private DNS server addresses provided by 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 used in 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.
