Structure of the namespace
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.
Process for new names below tu-dresden.de
New names directly below tu-dresden.de need prior approval by the university management via Sachgebiet 7.5: Web und Video :
01. The request is to be sent by a ticket (email) to Web Support. The ticket must contain the following information:
- Desired name of the subdomain(s) under "tu-dresden.de"
- Reason and description
- Desired DNS entries (e.g. IP address)
02. Examination and consultation by SG 7.5 Web and Video
- Prüfung der Vorrausetzungen (§ 18 IT-Ordnung)
- Consulting on hosting possibilities (VM at ZIH, webspace, WebCMS, external)
- Examination of design (Corporate Design rules) and if necessary support with agency assignment
- Advice on data protection and imprint (templates or involvement of Sachgebiet 3.5: Informationssicherheit if necessary)
- Advice on and review of accessibility
- Advice on other services for a domain (TLS certificates and mail)
03. Submission of resolution by SG 7.5 to the CDIO
04. Signed resolution for applicant (for submission to D1) and documentation
05. Registration of the subdomain by ZIH
Expiration time
DNS records have an expiration time (time to live/TTL), so that they need not be queried permanently anew and can be cached by querying systems (Caching). This expiration time must be considered when changes are planned. The default expiration time of DNS records in the ZIH name service is a day (86400 seconds).
If this expiration time is too long, it must be reduced before a change. If you need this, state this clearly in your change request.
