Version
Service Point v4.x.x
Once you have deployed DNS resolver service to a service point, you can modify the list of IP addresses attached to DNS resolver service when making a change to the service point IP addresses.
Attention:
  • You can only modify the service point network configurations if there are no services bound to the IP addresses being modified. If you have any services listening on the IP addresses to be modified, you must first update the service so that it no longer listens on this address.
  • Modifying the IP address of the DNS resolver service drops any stored offline query logs.
  • You cannot edit DNS resolver service when the DNS resolver service version is 3.9.x and below or the service point version is 4.5.x and below. You can only edit DNS resolver service when the DNS resolver service version is 3.10.0 and greater deployed on service point v4.6.0 and greater.
To modify the DNS resolver service:
  1. In the top navigation bar, click and select DNS resolver services.
  2. Click the name of a DNS resolver service. The DNS resolver service details page appears.
  3. Click Edit.
  4. Under Service IPs, select one of the following options to bind IP addresses to the DNS resolver service:
    • Listen on all primary (IPv4 and IPv6) addresses: the DNS resolver service listens for queries on all configured primary IP addresses configured on the Service Point v4 instance.
    • Listen only on specific addresses: the DNS resolver service listens for queries on specified IP addresses. Once you select this radio button, the select the following IP addresses:
      1. Select the checkbox next to the Primary IP address to associate with the DNS resolver service.
      2. If you have configured Anycast service on the service point, select the checkbox next to the Anycast IP address to bind to the DNS resolver service.

        For more information on configuring Anycast service on the service point, refer to Configuring Anycast service on Service Point v4.

      3. If you configured any Alias IP addresses, select the checkbox next to the Aliases IP address to bind to the DNS resolver service.
      4. If you have configured DSR VIPs on the service point, select the checkbox next to the Direct server return (DSR) IP address to bind to the DNS resolver service.

        For more information on configuring DSR VIPs on the service point, refer to Configuring the DSR VIP on Service Point v4.

  5. Click Update.
Note: Clicking the Update button queues the deployment task on the associated service point and does not indicate that the DNS resolver service has been immediately deployed. The deployment process can take a few minutes to successfully complete.
