What Are the Private DNS Server Addresses Provided by the DNS Service?

Updated at: Feb 21, 2020 GMT+08:00

Private DNS servers are used in VPCs to:

  • Resolve private domain names and internal domain names of other cloud services, such as OBS and Workspace.
  • Forward domain name requests to public DNS servers.

Compared with the public DNS server 114.114.114.114, private DNS servers provided by the DNS service have the following advantages:

  • Resolve private domain names created within VPCs.
  • Access internal addresses of cloud services like OBS and SFS.
  • Allow ECSs not assigned with EIPs to access the Internet.

Table 1 lists private DNS server addresses provided by the DNS service in different regions.
