Checking your network connection!
All devices attached to the CERN network should be registered, using a suitable device name. This applies also to portable computers to be used on "portable" outlets. The registration form http://network.cern.ch/register is also used to check and update information, as well as requesting moves, change of service type and temporary/permanent removal.
A very important part of the information for a device is the ethernet address which it will use. This information is a fixed part of the device (more precisely, the interface of the device to the network). Frequently, a new device registration is made before this information is known. We therefore ask users to supply it as soon as possible. The method to find this information varies according to the device and software being used.   The ethernet address is 12 hexadecimal (0-9, A-F) digits, of which the first six specify the maker of the interface and the last six are unique. On some systems this address is already printed on a label, either outside the system or inside on the interface card which has the network connector.
