# DNS Lookup Scout

The DNS Lookup Scout tests the availability and health of DNS servers, and whether the response of a query for a selected domain returns the desired result.

## Create a DNS Lookup Scout

1. In the Synthetic Monitoring top bar, click **Create Scout** to open the **Add New Scout** window
2. From the **Infrastructure** tab, select **DNS Lookup** as the Scout **Type**.
3. Select the locations (**Hives**) from which you want to initiate the DNS lookup test.
4. Enter the **Hostname** to test.
5. Enter a **Name** for the Scout.
6. Select a run interval for the test using the **Run Every** slider. For the first 10 minutes of the run, you can choose intervals of 1 to 10 minutes. After that, you can choose increments of 5 minutes up to 60 minutes (5, 10, 15, 20, and so on).
7. Optionally, add **Tags** to your Scout. Tags are key-value pairs which can be used to organize your Scouts. To learn more about tags, visit [Centralized Tags Management](/v1/docs/centralized-tags-management).
8. Optionally, click **Show additional parameters** to configure the following:
  - **DNS Server**. Sets the DNS server to use for the query. If you do not enter a value, the test uses the default DNS server of the selected Hive.
  - **Expected IP Response**. Sets an IP address that is used to determine if the test is successful. If the query responds with the IP address, then the test succeeds; otherwise, the test fails.
  - **Type**. Sets the query type A or MX.
  - **Timeout**. Sets the maximum wait time for the test to finish.
9. Click **Next: Alert Policy** to set up alerts and notifications on the Scout before saving it. For more information, see [Alert Policies](/tim-reorg/docs/alert-policies).

## Test Results

Click on a test result to see the full details of the DNS lookup test. In this example, you can see the type of information that is returned for a DNS lookup test to controlup.com.

You can see a summary of the Scout configuration, along with the resulting IP address and response time.
