Hi,

> How will this help a network admin, when the system log says, that a server that is supposed to have a certain fixed IP or a DHCP client, that is also supposed to have a certain fixed IP (however, one assigned by DHCP) cannot obtain this IP, because some other host with privacy extension enabled is currently using this IP by plain coincident?

The chance of this happening is *very* *very* small. I would worry more about people choosing such an IP address intentionally to cause trouble...
