Plan A Apply the full technological resources of the Network in a ruthless and unrelenting pursuit of the offenders. Ethernet hardware addresses can be backtracked through intelligent switches and hubs to a specific UTP wall port. Your team will then confront subversive elements, preferably late at night. The team should wear dark trenchcoats. Plan B Establish simple procedures such that anyone who wants an IP address (and cannot or prefers not to use a DHCP server) can obtain one, preferably in a matter of minutes. Network administrators respect the personal diginity of users.
