# Set up your IONOS domain

When setting up your **Client Portal** on Hubflo, you'll see the option to use either a **custom domain** or a **Hubflo subdomain**. This guide walks you through how to connect your IONOS domain in a few quick steps.

## What you’ll need before you start

-   A registered IONOS domain (e.g. yourdomain.com)
    
-   An active Hubflo subdomain (e.g. yourcompany.hubflo.com)
    
-   Hubflo Plus Plan
    

# Add your custom domain in Hubflo

1.  In Hubflo, go to **Settings → General Settings/Domain**
    
2.  Click **Edit domain**
    
3.  Enter your custom domain (e.g. `portal.yourdomain.com`) in the **Custom domain** field and click **Next**
    

# Add a CNAME record in IONOS

1.  Log in to your **IONOS account**
    
2.  Navigate to the **Domains** section
    
3.  Next to your domain, click the gear icon (⚙️) and choose **Manage Subdomains**
    
4.  Click **\+ Add Record**
    
5.  Select **CNAME** from the record type options
    

**Fill in the fields as follows:**

-   **Host Name**:  
    ​`portal`, `client`, `www`, etc. (depending on the subdomain you want to use—e.g., `portal.yourdomain.com`)
    
-   **Target**:  
    ​`portal.hubflo.com` ← _make sure this is exact and not changed_
    
-   **TTL**:  
    You can leave this as **automatic**
    

Click **Save**, then confirm the change on the next screen

**Note:** Your changes are effective immediately in IONOS. However, it can take **up to an hour** for the changes to fully propagate.
