  • ZSD can register .co.za, .com, .net, .org, .org.za, .net.za, .co.uk, .capetown, .joburg and many more domain names.
  • Domain names are registered to the end user, and thus you have the option of keeping your domain name if you ever wish to change to a new ISP.
  • We manage domain registrations under exotic and unusual hierarchies, like Top Level Country Codes for various African states and off shore islands. Contact us for advice on availability, costs and restrictions like language and residency.
  • Please note domain registrations are subject to conditions and regulations prescribed by the authorities responsible for each domain hierarchy.
  • Contact ZSD to determine the availability of your preferred domain names and for suggestions on possible alternative names and domain hierarchy's.

You can use the domain for your email address and webpage e.g yourname@yourdomain.co.za and www.yourdomain.co.za. Please note that domain registration only reserves the domain for your use, email and web hosting services need to be contracted separately.
