By default, in DNSmanager users cannot add a domain if it is a subdomain owned by another user. Shared domains allow creating a domain where reseller's users can create their subdomains. 

Note

Only Resellers can create shared domains.

Perform the following steps to create a shared domain:

  1. Navigate to Settings→ Shared domains → Add.
  2. Enter a  Domain name.
  3. Set the Domain limit — this is the maximum number of subdomains that every user can create on a shared domain. 
  4. Click Ok.
