This guide shows you how to add an addon domain to your HOSTDOG hosting account so you can run an entirely separate website — with its own files, databases, and email addresses — without needing a second hosting plan.

Prerequisites

  • An active HOSTDOG hosting plan that supports addon domains (check your plan's limit in the client area)
  • A registered domain name pointed to HOSTDOG's nameservers (ns1.hostdog.gr and ns2.hostdog.gr) — see How to change your nameservers
  • Access to your hosting control panel (how to log in)

Add an addon domain

Step 1:
Log in to your control panel

Navigate to the HOSTDOG homepage and click the Log in button in the top-right corner. From your client area, go to your hosting service and click Login to Control Panel.

Step 2:
Open the Domains section

In your control panel, find the Domains section and click Addon Domains (or Domains in newer panel versions). This is where you manage all additional domains on your account.

Step 3:
Enter the new domain name

Type your domain name in the New Domain Name field (e.g., myotherdomain.com). The Subdomain and Document Root fields are usually auto-filled:

  • Subdomain — automatically created as an internal reference (e.g., myotherdomain).
  • Document Root — the directory where this site's files will live (e.g., /home/youraccount/myotherdomain.com or /home/youraccount/public_html/myotherdomain.com). You can change this to any path you prefer.
Step 4:
Add the domain

Click Add Domain to create the addon domain. The control panel will create the document root directory, set up the DNS zone for the domain, and configure the necessary web server settings.

Tip: After adding the domain, upload your website files to the document root directory you specified. You can use the File Manager or an FTP client to do this.
Step 5:
Verify the domain is working

Open your browser and navigate to the new domain. If the nameservers are already pointed to HOSTDOG, you should see the content from the document root directory (or a default index page if no files have been uploaded yet). DNS propagation may take up to 24-48 hours if you recently changed the nameservers.

Frequently asked questions

How many addon domains can I add?

The number of addon domains depends on your hosting plan. Check your plan details in the HOSTDOG client area under Services to see your specific limit. If you need more, consider upgrading to a plan with a higher allowance.

Yes. All addon domains share your hosting account's CPU, memory, I/O, and disk space allocation. If you host several high-traffic sites, monitor your resource usage to ensure your plan has enough capacity.

Yes. Once an addon domain is added, you can create email accounts for it just like your primary domain. Go to Email Accounts in your control panel and select the addon domain from the domain dropdown when creating a new email address.
