DNS Resource Records

Overview

Each zone in the Domain Name System (DNS) contains a set of resource records that define how requests are processed or delegated within that zone. To view the resource records for a particular zone, you can double-click the zone, or select the zone and then click Open on the task bar at the top or on the Row … menu. Once you have opened the zone, you can view, edit, and manipulate the resource records.

Creating New DNS Records

Note

For importing DNS records in bulk, see Importing DNS Records.

To create a new DNS record:

  1. Click Create in the main toolbar. The Create DNS Record dialog box opens.

  2. Enter a name and select the record type. After selecting the type, the relevant fields are automatically displayed.

Warning

If you save a new DNS record with the wrong type, you cannot change the type later. You have to delete the record and create a new one with the correct type.

  1. Enter the required information and custom fields, if applicable.

    • For A records, an autocomplete behavior helps find a free IP address in a network.

    • When you enter the first digits of a network, you’ll see a list of networks to choose from.

  • Selecting an item from the list will fill in the Address field with the next free IP address from that network, along with an indicator on the address state: Free, Reserved, Claimed or Assigned. You’ll also see insights for the selected IP address.

  1. When you are finished, click Create now to save the new record to the zone or Add to request to add it to the request queue. For more information about the request queue, see Workflow.

It’s also possible to create DNS records through the Micetro API.

IP Address Insights

Once you have entered/selected the IP address in the Address field, you can see some insights about the address and related objects. These insights provide more information about the IP address and can help you to better understand its state.

  4. Click Save.

Deleting Records

Deleting a record removes both the data and the physical record from the grid.

To delete a DNS record:

  1. Select the record(s) that you want to delete. To select multiple records, hold down the Ctrl (or Cmd on Mac) key while making your selections.

  2. Click Delete on the task bar. The record is immediately deleted from the zone.

Undoing Changes to Records

If you need to revert or undo changes made to DNS records, Micetro provides a straightforward process through its history feature. It’s essential to use this feature carefully, especially when dealing with critical DNS configurations.

To undo changes:

  1. Locate the zone where the changes were made, and click on the row menu (…) associated with it.

  2. Select View history.

  3. Locate the specific action you want to undo within the history.

  4. Select Undo option on the Row menu (…). This action will roll back the selected change, restoring the DNS record to its previous state.

For more information about viewing object change history, see Viewing Object Change History.
