This article explains how to add DNS records for a subdomain within an existing parent zone in UltraDNS. For example, you can add records for sub.example.com within the example.com zone.

This procedure keeps the subdomain records in the parent zone. To create the subdomain as a separate primary zone, use the related article below.

When to Use This Article

• You need to add DNS records for a subdomain within an existing UltraDNS zone.
• You want to manage those records within the parent zone.

Prerequisites

• Access to the UltraDNS account with permission to add records to the parent zone.
• The parent zone already exists in UltraDNS.
• The required hostname, record type, and record values.

Add the Subdomain Records

1. Log in to the UltraDNS portal.
2. Click Domains.
3. Select the parent zone, such as example.com.
4. On the Records tab, locate the record type you need and click Add Record.
5. In the Host field, enter the subdomain hostname, such as sub.example.com.
6. Complete the required fields for the selected record type.
7. Click Save.
8. Repeat these steps for each additional record you need.

Verify the Saved Records

After saving, the record appears under its record type on the Records tab. Confirm that the hostname, record type, and saved values match the information you intended to enter.

Create a Separate Subdomain Zone

A subdomain can also be configured as a separate primary zone. For instructions on creating that zone and configuring delegation within the same account, see Creating standalone subdomain/subzone.
