  • About the issue which the DHCP server of the logical network announces an unintended cache (resolver) DNS server addressBaremetal Server, Common Function Gateway, ECL2.0, Logical Network, Virtual Server

    Overview of the Issue

    • The DHCP server of the logical network delivers an IP address (IP address of the DHCP server) that the customer does not intend as the IP address of the cache (resolver) DNS server.
    • If the OS of the virtual server instance or the bare metal server acquires the IP address (DHCP server IP address) that the customer does not intend as the IP address of the cache (resolver) DNS server by DHCP, the global name space name can be resolved.* Enterprise Cloud 2.0 does not offer cache (resolver) DNS server.

          • nmcli connection show <interface name connected to the logical network>

    Solution

    The solution is as follows.

    1. When it is necessary to acquire the IP address of the cache (resolver) DNS server by DHCP
      • Please perform the following setting in "Edit Subnet".
        • DNS Server: Enter the IP address of the cache (resolver) DNS server in the text box (* 1)
    2. When it is not necessary to acquire the IP address of the cache (resolver) DNS server by DHCP
      • Please perform the following setting in "Edit Subnet".
        • DNS Server: Check the "Disable DNS Server" check box. (* 2)

    * 1 We do not offer cache (resolver) DNS server in Enterprise Cloud 2.0. Therefore, please specify the IP address of your internal DNS server and the IP address of the cache DNS server provided by the customer's selected public DNS service.

    * 2 In the case of API, enter 0.0.0.0 in the DNS server section.

    Schedule

    We plan to change the setting of the logical network of existing customers and stop delivery of an unintended cache (resolver) DNS server address.

    If you need to take action before then, please take measures to deal with delivery / distribution of DNS server addresses referring to the above mentioned actions.
