The IP address of every computer connected to the CTNET must be properly registered using an authorized Network Address and a registered network card. If not, these computers will be considered as illegal and be blocked from accessing the campus network as soon as they are discovered. In order to avoid interruption due to blocking arising from the "unregistered" status, the registration information regarding the network connection of each computer must be checked and if necessary, updated every now and then. To do the checking, simply click on the "My Network Connection" icon under the Intranet menu and then follow the instructions displayed there.
If discrepancies are found, the registration record in the network database must be amended by the Departmental Network Administrator (DNA) as some privileged data of the registration record are protected and can only be updated by the DNA concerned. Various scenarios of the checking and amending procedures have been published on the Web. For a detailed operation and procedure guide, please click here.
As users are fully accountable for the activities they conduct on the network from their PCs, and the MAC addresses and IP addresses assumed by these PCs are serving as the identity of their respective users, in order to prevent unauthorized uses of these addresses, users are therefore reminded of the following:
