**Create a Subdomain**

To create a subdomain, you will need to add a new DNS record. Follow these steps:

**Click the "Add record" button** (Add record).

**Choose the record type as "CNAME", enter the subdomain name and point it to "sh.sprinthub.site".**

{% hint style="danger" %}
Disable the proxy option; with it enabled you will not be able to configure the connection with Sprinthub
{% endhint %}

After configuring the necessary fields, click save and verify that the record was added correctly in the DNS records list.

### Domain validation

{% hint style="info" %}
You must point for AWS validation.

* **Instructions**:
  1. Access your domain's DNS records.
  2. Add a new record in the DNS settings selecting CNAME as the record type.
  3. Return to the first window, copy the content of the "Name / Host" field.
  4. Paste the copied content into the "Name or Host" field of your DNS records.
  5. Go back to the first window and copy the content of the "Value / Target" field.
  6. Paste the copied content into the "Value or Target" field of your DNS records.
* **Verification CNAME record**:
  * **Record Type**: CNAME
  * **Record Name "Name / Host"**: A generated value appears (a unique alphanumeric code).
  * **Value "Value / Target"**: A specific generated value (also an alphanumeric code), pointing to an AWS domain for validation.

These instructions are to ensure the custom domain is validated correctly when configuring the CNAME record on the DNS server.

{% hint style="info" %}
A CAA validation is required on Cloudflare so it can pull the certificate information.
{% endhint %}

There are two types of CAA - Issue and Issuewild for Amazon.com
