How to Connect a Subdomain to Hostinger Website Builder (Step-by-Step Tutorial)

June 17, 2025

If you’re building your website with Hostinger Website Builder and want to connect a subdomain (e.g., blog.yoursite.com), this guide walks you through the process step by step. Whether you’re using Hostinger’s domain registrar or another provider like GoDaddy or Bluehost, the instructions below will help you set everything up correctly.

Step 1: Access Your Website Settings in Hostinger

  1. Log in to your Hostinger account.
  2. Navigate to the Websites section and select your site.
  3. Click Edit Website next to the project built with the Hostinger Website Builder.

If your website still uses a temporary domain, now is the time to replace it with your custom subdomain.

Step 2: Connect Your Subdomain

  1. Click Edit Website, then go to Connect Domain.
  2. Hit Change Domain and enter your subdomain (e.g., book.yoursite.com).
  3. Click Yes, then Next to proceed.

Your subdomain is now associated with your website, but it won’t be live until you update your domain’s DNS settings.

Step 3: Update Name Servers in Your Domain Provider

If your domain is hosted outside of Hostinger (e.g., GoDaddy, Bluehost), log in to your provider’s dashboard. Look for DNS or Name Server settings.

  • Replace the current name servers with Hostinger’s default name servers.
  • You can either manually enter them or select the option to use Hostinger’s name servers.

If your domain is already registered with Hostinger:

  1. Go to the H Panel, then click on Domains.
  2. Select your domain, then Manage.
  3. Find the DNS/Name Servers section.
  4. Click Change Name Servers, delete the current entries, and enter Hostinger’s name servers.
  5. Click Save.

Step 4: Wait for Propagation

DNS changes may take up to 24 hours to propagate. During this period, your subdomain might not load immediately — this is normal. In many cases, it connects within 10–15 minutes, so be patient.

Step 5: Verify Everything Works

Return to your website dashboard in Hostinger and try visiting your subdomain. Once DNS has propagated, your subdomain will be fully connected and serving your Hostinger-built website.

By following these steps, you can easily connect a subdomain to your website using Hostinger Website Builder, giving your brand a more professional online presence.
