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. New names directly below tu-dresden.de need prior approval by the university management.
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.
