Registration Types:

Client - this type of registration can be requested by any member of staff or postgraduate student. Machines registered as clients are not required to provide a service e.g. web site hosting, printing etc., and are not intended to be accessible outside of the VLAN in which they are active. Clients have full access out of the VLAN. Control of access into the VLAN is a measure to increase the security of your machine.

Server - this type of registration can only be requested by a member of staff. A machine registered as a server is accessible by users both outside of the VLAN on which they are active and outside of UCD. Customers registering servers which are required to be accessed outside of UCD should do so following the instructions on the Security web page.

Printer - All printers need to be registered in order to work on the UCD Network. Once registered, printers will not be accessible outside of the VLAN in which they are located. Printers which are required to be accessed outside of the VLAN should be registered as servers (see above).

Administrative Roles:

Each machine registered for use on the UCD Network must be the responsibility of an identified individual, its owner.

For a server or printer, the technical aspects of management of the machine are the responsibility of an administrator, who may be the same person as the owner.

In addition, an emergency contact is required who must be different from the administrator and the owner.

Preferred Hostname:

A preferred hostname is required for every server and printer. For client machines, this information is optional.

Hostnames must be composed of letters, digits and hyphens. They should be at least five, and preferably no more than fifteen, characters long. A hyphen may not be used as either the first or the last character of a hostname. It is also recommended not to use a digit as the first character.

Examples of valid hostnames:

  • rainbow
  • car-park
  • par-3

Ethernet Address:

Your Ethernet Address (also 'Hardware Address' or 'MAC Address') is a 12 character alphanumeric code, which uniquely identifies your machine. Your ethernet address can include the letters 'a' to 'f' and the digits '0' to '9'. It is usually written as six pairs of characters, with a colon (':') separating each pair from the next.

Example: 00:08:4a:f9:d5:30

You can find this on most Windows machines by going to Start / Run / type "cmd" or "command" and then typing "ipconfig /all" at the command prompt. The Ethernet address is listed as "physical address" under "Ethernet adapter Local Area Connection".

On Linux or Unix machines type "/sbin/ifconfig".

For further assistance please contact the Helpdesk at ext. 2700.

Services Offered:

Please give a short description of the services which your server or printer will offer, and the intended community (for example: entire Internet, UCD only, specific school, unit, or group) which will avail of these services.

For further assistance please contact the Helpdesk at ext. 2700.

Area Type:

This is the type of area in which the machine is normally located. A public area is an area to which access is not restricted by key or electronic swipe to a small number of persons. A private area is an area to which access is restricted, such as an office.

Telephone Number:

Please enter your telephone number either as a four-digit UCD extension or as a full international number in the recommended standard format (beginning with "+").


  • 7777 (UCD extension)
  • +353-1-716-7777 (the same, as a full international number)
  • +353-87-xxx-yyyy (mobile number from "087" range)
