Creating a sub domain on your Web Hosting
This FAQ will help you to set up a sub domain.
Subdomains are used to compartmentalise areas of a website or to offer different versions of the same website.
For example, you could use a subdomain to separate your online shop from the rest of your domain, using store.mydomain.com. Or, you could use en.mydomain.com and de.mydomain.com for English and German language versions of your site respectively.
Log in to your 123 Reg control panel
Scroll down to the Web hosting section.
Select your domain name using the drop-down menu and then click on the Manage button.
In the Web Tools section, click on Sub Domains.
Now type in the sub domain.
You can now type in the directory folder for your website files, or leave it blank if you wish for your sub domain to point to your main website.
Click on Create.
Your sub domain has been created and it will appear in the Modify Sub Domains section.
Please note: Sub domains can take up to 1 hour to become active.
