Domain extensions with Hoststar

Support > Domain > Domain information

All domain-name extensions can be activated on Hoststar servers.

  • We can register domain extensions (top-level-domain – TLD) listed on the website for you. We also offer useful tips on how to change domains.
  • To use externally registered domains on our servers, you need the login details for the administration of the desired domain.

Detailed information on changing name servers can be found here.
