<span style="color: #000000">After you have successfully deployed Universal DDI on a NIOS-X Server, you can start configuring global DNS properties and DNS configuration profiles to enable the DNS service on the NIOS-X Server. The DNS server resolves NIOS-X Server names to IP addresses and supports 500 queries per second. </span>

> 📝 NIOS-X allows DNS configuration updates to be applied sequentially on NIOS-X servers, even when you schedule software updates. Configuration updates are performed one NIOS-X server at a time, progressing to the next server only after the configuration on the current server has been updated successfully. For information, see *[Scheduling Configuration Updates for Servers](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneInfrastructure/pages/184583817)*.

<span style="color: #000000">In addition, Universal DDI supports the following:</span>

- <span style="color: #000000">Primary authoritative DNS</span>
- <span style="color: #000000">Secondary authoritative DNS</span>
- <span style="color: #000000">DNS server groups</span>
- <span style="color: #000000">Access Control List (ACL) templates</span>
- <span style="color: #000000">Recursion</span>
- <span style="color: #000000">Forwarding</span>

<span style="color: #000000">With the BloxOne Threat Defense license, you can also configure DNS Forwarding Proxy on the same NIOS-X Server that is running Universal DDI DNS. For more information, see </span><u><span style="color: #003366">*[Configuring DNS Forwarding Proxy and BloxOne DDI DNS](https://infoblox-docs.atlassian.net/wiki/pages/createpage.action?spaceKey=bloxoneddi&title=Configuring%20DNS%20Forwarding%20Proxy%20and%20BloxOne%20DDI%20DNS&linkCreation=true&fromPageId=186810605)*</span></u><span style="color: #000000">.</span>

**DNS service performance**: The table displays a DNS server's performance in terms of service restart and expected DNS server update interval times depending on how many zones and records it has configured, to start responding to changes made by a user.

| **Authoritative Zones** | **DNS Records** | **Service Reload Time (seconds)** | **Expected DNS Server Update Interval (minutes)** |
| --- | --- | --- | --- |
| 5,000 | 25,000 | 17-22 | 1.6 |
| 6,000 | 30,000 | 17-22 | 2.2 |
| 7,000 | 35,000 | 17-22 | 2.2 |
| 8,000 | 40,000 | 33-39 | 2.2 |
| 10,000 | 50,000 | 44-50 | 2.2 |
| 11,000 | 55,000 | 44-50 | 6.6 |

Note: **Expected DNS Server Update Interval** refers to the time it takes for a DNS configuration to be sent from the Infoblox Portal to the NIOS-X Server running in your environment.
