What is a subdomain?

A subdomain is an extension of your main domain, in the form blog.example.ro or shop.example.ro. Technically it is just a DNS record (usually of type A or CNAME) added to the main domain's zone.

A subdomain can point to:

  • another folder or application on the same hosting account;
  • a completely different server or service (for example an online shop hosted separately).

Subdomains are not registered with the registry (EURid/RoTLD) and don't involve extra costs — they're created and removed directly in the domain's DNS zone, either from your EUReg customer account (if you use EUReg's nameservers) or from your hosting provider's control panel.
