Host names must be no longer than 15 characters (a restriction imposed by Windows).

The basic structure of a host name is:

This is what it means in detail:

  • OOO (max. 3 characters): the organizational unit (OU) that the device is operated for
  • TT (max. 2 characters): the type, e.g. server = sv, workstation = ws, notebook = nb, ...)
  • IIIIIIII (max. 8 characters): info field; can be designed by each computer administration group (RBG) according to their individual needs (e.g. with notebooks: the chair or location, with workstations: the name of the series, etc), and - if you want to - the info field may contain a serial number

Note: None of the field names may contain further hyphens, and it must be a valid host name


  • dmz-sv-cal
  • z-sv-filer
  • th-sv-filer1
  • th-ws-i715
  • cip-ws-101
  • th-nb-delft01
  • gar-nb-etp01

Handling exceptions

On principle, you should not deviate from the nomenclature; however, there may be cases where deviations cannot be avoided. This applies in particular to very old systems or measuring systems (such as the PowerPCs in Garching). In these cases a nomenclature-compliant name should at least be given as an alias.

User-defined aliases are still allowed and can be given without a prescribed name structure. But please note that that all internally used services must be given unambiguous service aliases that allow permanent access to these services. The underlying nomenclature-compliant name can change, but the service name must remain unchanged (e.g. www->z-sv-web01 on www->z-sv-web02).

Exception Web services: These are generally assigned as virtual hosts on the web server. In this case the nomenclature name applies only for the server itself (on the IP of which no web service will run). The websites themselves will only be given the service name. Example:

  • -> - server, but no port 80/443
  • -> - virtual server on dmz-sv-static

Please note: New short names for organizational units (OUs) may be introduced only after consulting all full-time members of the computer administration group.

Use of the information field (max. 8 characters)

There is no exact definition of the use of the info field.
The computer administration groups (RBGs) will define the info field themselves as they consider it as reasonable.

Examples: filer, delft01, 101, 102, 201, 202
