What's a subdomain?

Subdomains allow you to have a new web address for separate areas of your website.

For example, Google has, in addition to its root domain (google.com), various subdomains for different services (e.g. mail.google.com).

Setting up a subdomain through your account is easy with the Heart Internet eXtend control panel.

Create a subdomain hosted in your eXtend Control Panel

To create one, log into your eXtend control panel and click 'Sub Domains' from within the 'Web Tools' pane.

To add a subdomain, you need to enter what you want the subdomain to be called and which directory it will point to.

For example you might want the subdomain support.yourdomain.com, where the files for the subdomain are held in yourdomain.com/support.

To delete a subdomain or change the directory that it points to you simply need to edit the details listed in the 'Edit Sub Domains' section.

Create a subdomain hosted on different IP addresses

You can also set up subdomains as A records in the DNS Management section.

This can only be done through our control panel if your domain uses our nameservers. If it uses external nameservers, the external subdomain would need to be set up on those nameservers.

Using this, you can set a subdomain to point at a specific IP address.

How long will it take to set up?

For subdomains set up within your account with us, it will take anywhere from 30 to 60 minutes for a subdomain to begin working as expected, whilst the update to your site's settings are processed.

If the subdomain is set up by changing the A records for your domain, the process can take a little longer, as the updates need to propagate around the world, which can take up to 24 hours to complete.
