In realtà solo alcuni di questi sono veri siti WWW.

Alcune macchine usano il WWW come interfaccia per la ammnistrazione, e tra queste ci sono le stampanti come cdc10, cdc2, cdcposso, cdcpp, cdcpt, cdcsd, 131.114.72.188, 131.114.72.233;
altre servono per prove come temp3 ... e altre sono state forse dimenticate con il demone httpd attivo come lab1 e studidott2
(in realtà il controllo fatto su studidott2 ha evidenziato un'altra storia e cioè una altra macchina stava per errore utilizzando l'IP di studidott2 ! - ed è stats subito staccata dalla rete !)
Le altre sono tutte funzionanti come server WWW fornendo al mondo varie informazioni, oppure vari servizi come i webmail per esempio.

Il Dipartimento ha comunque anche altri server Web su altre LAN.
