The DNS namespace has a hierarchical structure and its components are separated via dots. The namespace below the domain tu-dresden.de is also structured hierarchically and consists mainly of subdomains of organizational units (e. g. faculties or central units) of TU Dresden.
External domains
Under certain conditions, in addition to names or subdomains under the tu-dresden.de domain, other own domains with other domain extensions can also be used. In almost every case, such domains are used partially or exclusively for the provision of websites, which is why the application for domains is integrated into the application process for own websites in order to enable comprehensive advice with a central point of contact. The legal framework is provided by the Regulations for the Information Technology Equipment and Services and for Information Security at TU Dresden (IT Regulations) (Dated: February 18, 2021).
Scope of Services
- External domains according to the IT regulations
- Registration / Transfer / Termination
Options
- all common Top-Level Domains (TLDs)
Application
- Application is made informally via Service Desk

Providers (registrars)
Domains are procured exclusively by the ZIH after approval by the CDIO within the framework of the DFNinternet service at DFN-Verein e. V. or via a framework agreement with the contractual partner INWX GmbH & Co. KG via a framework agreement. Decentralised procurement of domains by the structural units is not planned. New registrations or renewals with other registrars are no longer permitted from 2021. Instead of a renewal, the domain must be transferred to one of the two authorised registrars as part of a provider change with the ZIH.
DFN
Domains with the domain extensions .de, .eu, .org, .com, .net, .info and others on request can be obtained via DFN. The costs are currently (as of 02/2021) EUR 36.00 net for the initial registration and EUR 36.00 net per year pro rata from the date of registration of the domain.
INWX
Domains with over 2.000 domain endings can be obtained via the framework agreement with INWX. The costs depend on the respective ending. The current prices for all available endings can be viewed in the INWX price list. For the TU Dresden, additional discounts may apply for corresponding volumes.
Endingspecific regulations
The registration organisations (registry) responsible for a domain extension, in the case of .de for example the DeNIC eG, have their own rules for domains with the respective extension. Please contact INWX to find out about the specific details for your desired domains. This includes special requirements (e.g. the holder of .eu domains must be an EU citizen/institution) and regulations regarding the storage, publication (e.g. via WHOIS) and forwarding of the domain holder's personal data and contact persons.
Authoritative DNS / name server
The authoritative DNS service (name server) for the domains is provided by the ZIH and the selected registrar (DFN or INWX). Information on changes and administration of DNS entries can be found there.
