A Certain Domain Name Cannot Be Resolved or the Resolution Result Is Incorrect

A Certain Domain Name Cannot Be Resolved or the Resolution Result Is Incorrect


A certain domain name cannot be resolved or the resolution result is incorrect.

Possible Causes

  • The domain name is not configured on DNS-Internal.
  • An incorrect mapping between the domain name and IP address is configured in the /etc/hosts file on the local host.

Troubleshooting Process

  1. Configure the domain name.
  2. Delete the incorrect configuration from the /etc/hosts file on the local host.


  1. Check whether you can log in to the VM on which DNS-Internal is deployed. The management-plane DNS is deployed on the OM-SRV01 and OM-SRV02 nodes, and the tenant-plane DNS is deployed on the TDNS-TNTP01 and TDNS-TNTP02 nodes.

    • If yes, go to 4.
    • If no, go to 2.

  2. Restore the VM. For details, see Cloud Platform Troubleshooting.
  3. Contact technical support to reinstall DNS. No further action is required.
  1. Enter http://DMK floating IP address:8443 in the address bar of the browser to log in to DMK.

    The default account is udns. The default password is cnp200@HW.

  2. In the navigation pane on the left, choose Deploy Guide.
  3. On the Service Configuration page, click the Services tab and select DNS-Internal.
  4. Set the following parameters:

    • Select Version: version of the installation package
    • Select Action: Domain Config
    • Select Region: local
    • Host Repository: NO
    • Blue-Green Deployment: NO

  5. Click Next to switch to the Hosts and User Configuration page.
  6. Select the DNS-Internal team and the udns account.
  7. Check whether the configuration file contains configurations of the domain name.

    • If yes, check whether the configurations are correct.
      • If yes, go to 11.
      • If no, correct the configurations and go to 11.
    • If no, add the required configurations of the domain name.

  1. Click Execute to start the configuration.
  2. Check the task status.

    1. In the navigation pane on the left, choose Task Board.
    2. Locate the task and view the status before the task name. The configuration is successful if the status changes to .
    3. Click Details in the Operation column to view task details.

  3. If the domain name still cannot be resolved, check whether the /etc/hosts file on the faulty node contains configurations of the domain name. If yes, delete the configurations. If the problem persists, contact technical support for assistance.
